UA-101 - UA-101, playback Pulseaudio fails to detect card

[Michael Mess]

This bug has been created with apport-bug.

After upgrade from 10.04, the UA-101 inputs and outputs seem unavailable in standard audio settings.
Sound works with VLC when UA-101 is selected via ALSA.

It is possible to load the alsa-sink device manually using the pulseaudio command line interface:

michael@quad:~$ pacmd
Welcome to PulseAudio! Use "help" for usage information.
>>> load-module module-alsa-sink device_id="0" rate=192000 channels=6 channel_map=left,right,aux0,aux1,aux2,aux3
>>>

Now the sound card is visible in the ubuntu sound configuration and the sound works.

[Michael Mess (michael-michaelmess)]

Here is some information about the UA-101 audio interface:

There is a hardware switch to select the sampling rate:
 * 44,1 kHz
 * 48 kHz
 * 88,2 kHz
 * 96 kHz
 * 192 kHz
The sampling rate selected by the switch will be applied when the device is turned on and cannot be changed while the device remains powered on. When the switch is changed while the device is on power, the sampling rate will not be applied until the device gets power-cycled.
It is not possible to change sampling rate by software.

For autodetection, pulseaudio could try the sampling rates, beginning with 192 kHz, to see, if the alsa device accepts the sampling rate and then choose the one which is accepted.

When using 192kHz, 6 channels are supported, for the other frequencies, 10 channels are supported.

[Michael Mess (michael-michaelmess)]

The version of Pulseaudion which is installed is:

Package: pulseaudio
State: installed
Automatically installed: no
Multi-Arch: foreign
Version: 1:1.1-0ubuntu15.1

After manually loading the driver with the load-module command like described above, sound works perfectly. :-)

[Michael Mess (michael-michaelmess)]

Remaining problem is that the card is not autodetected and the driver needs to be loaded manually each time when the user logged in.
Maybe we have to add something like a card profile or card detection script for loading the alsa module correctly when the card has been detected.
Could anybody give me some links for useful documentation how cards are detected and how to write such scripts?

[Michael Mess (michael-michaelmess)]

When the card is loaded, syslog shows:

[Michael Mess (michael-michaelmess)]

Testing by manually loading the module with the arguments from the log showed me that the card_name argument may cause the failure.

>>> load-module module-alsa-sink device_id="2" rate=192000 channels=6 channel_map=left,right,aux0,aux1,aux2,aux3 name="usb-EDIROL_UA-101_ZT82634-00-UA101" card_name="alsa_card.usb-EDIROL_UA-101_ZT82634-00-UA101"
Module load failed.
>>> load-module module-alsa-sink device_id="2" rate=192000 channels=6 channel_map=left,right,aux0,aux1,aux2,aux3 name="usb-EDIROL_UA-101_ZT82634-00-UA101"

Further tests to isolate the cause of the failure will follow...

[Michael Mess (michael-michaelmess)]

Then I tried:

>>> load-module module-alsa-sink device_id="2"

and it was successful, but there was a surround setup for the speakers which does not fit to my current audio connections, thus I have to add the channel map arguments.

It worked, thoughout I didn't specify the rate=192000, so it seems that not specifying the rate was not the problem what I have thought before.

[Michael Mess (michael-michaelmess)]

From the logs:

Jul 18 12:29:24 quad pulseaudio[2932]: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="usb-EDIROL_UA-101_ZT82634-00-UA101" card_name="alsa_card.usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes card_properties="module-udev-detect.discovered=1""): initialization failed.

Loading module without specifying card_name and card_properties arguments works:

>>> load-module module-alsa-sink device_id="0" name="usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes

By the way, I have noticed that after rebooting, the device_id changes randomally, sometimes the UA-101 is card0, sometimes card1 and sometimes card2, but that is correctly recognized.

[Michael Mess (michael-michaelmess)]

Loading the module alsa-source for recording can also be done manually with pacmd, for example:

>>> load-module module-alsa-source device_id="0"

Recording sound with the gnome sound recorder seems to work well.

[Michael Mess (michael-michaelmess)]

On the link, there is a list of valid arguments, probably the arguments card_name and card_properties should be specified correctly as sink_name and sink_properties.

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/module-alsa-sink.c

static const char* const valid_modargs[] = {
    "name",
    "sink_name",
    "sink_properties",
    "namereg_fail",
    "device",
    "device_id",
    "format",
    "rate",
    "alternate_rate",
    "channels",
    "channel_map",
    "fragments",
    "fragment_size",
    "mmap",
    "tsched",
    "tsched_buffer_size",
    "tsched_buffer_watermark",
    "ignore_dB",
    "control",
    "rewind_safeguard",
    "deferred_volume",
    "deferred_volume_safety_margin",
    "deferred_volume_extra_delay",
    "fixed_latency_range",
    NULL
};

[Michael Mess (michael-michaelmess)]

That was the reason. With sink_name and sink_properties it works.

>>> load-module module-alsa-sink device_id="0" name="usb-EDIROL_UA-101_ZT82634-00-UA101" card_name="alsa_card.usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes card_properties="module-udev-detect.discovered=1"
Module load failed.
>>> load-module module-alsa-sink device_id="0" name="usb-EDIROL_UA-101_ZT82634-00-UA101" sink_name="alsa_card.usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes sink_properties="module-udev-detect.discovered=1"
>>>

[Michael Mess (michael-michaelmess)]

In the log files, there was written: "Failed to load module "module-alsa-card"".

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/module-alsa-card.c

So the module-alsa-card takes the arguments card_name and card_properties and I used module-alsa-sink and module-alsa-source where this is different and that confused me a bit.

There must be another reason why the module-alsa-card fails:

>>> load-module module-alsa-card device_id="0" name="usb-EDIROL_UA-101_ZT82634-00-UA101" card_name="alsa_card.usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes card_properties="module-udev-detect.discovered=1"
Module load failed.
>>> load-module module-alsa-card device_id="0" name="usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes
Module load failed.
>>> load-module module-alsa-card device_id="0"
Module load failed.
>>>

I'm seeing the same problem with my UA-1000 (which uses the UA-101 driver). I think the OP has covered all the bases, but I'm pasting the lsusb -vvvv for this device since it is a different model number. Let me know if you want any other info.

Edirol UA-101 card is not autodetected by PulseAudio and the driver is not loaded.
Therefore it cannot be used using PulseAudio without manual interaction (See workaround).
It works properly when accessed directly via ALSA.

There is a workaround to load the pulseaudio driver manually with the following script: (I have turned the frequency selector to 192kHz.)

#!/bin/bash
echo 'load-module module-alsa-sink device_id="'$[$(cat /proc/asound/cards |grep UA101| cut -d'[' -f1)]'" rate=192000 channels=6 channel_map=left,right,aux0,aux1,aux2,aux3' | pacmd

The UA-101 is an USB device that has a hardware switch to select sampling frequencies:

192000 Hz, 6 Channels
96000 Hz, 10 Channels
88200 Hz, 10 Channels
48000 Hz, 10 Channels
44100 Hz, 10 Channels

When using 192000 Hz sampling rate, only 6 channels are supported, while otherwwise the card supports 10 channels.

Specifications: See http://www.rolandus.com/products/details/703/specs/

post the pulseaudio verbose log

AS your usb audio does not has any volume controls

Do your usb audio support stereo playback / capture ?

 do you load module-switch-on-port-available ?

[Michael Mess (michael-michaelmess)]

Upgrading to Ubuntu 14.04 fixed the issue for me. :-)
Sound is available, without the need to manually apply the workaround or changing configurations, etc.

So you should consider upgrading to Ubuntu 14.04.

But now I am still fighting with the proprietary NVIDIA graphics card driver in 14.04 (See #1313274, if you have an NVIDIA card) :-(

[Michael Mess (michael-michaelmess)]

Upgrading to Ubuntu 14.04 fixed the issue for outgoing sound only.

Inputs (Microphone, etc.) are still not available, but I didn't have time yet to test if there is a workaround how to get it working.

This should be fixed with the multichannel patch in git head. Please test it and reopen this bug if it isn't fixed. Thanks!

[Joe Clifford (joeclifford)]

I've done a quick compile and test of the pulseaudio git head code on Ubuntu 14.04 and it does indeed now autodetect and automatically sets up the multichannel audio outputs - running the compiled pulseaudio git binary detects the UA-101 and sets it up as a 7.1 multichannel audio output device in the gnome sound/volume control.
However, the git binary doesn't detect my motherboard's onboard HDA Intel PCH sound card (like the default pulseaudio in ubuntu does), it only detects the UA-101 and then only the audio outputs, not the audio inputs. Probably something to do with a module or conf not loading as I'm running pulseaudio from my home source directory.

Hi Joe and thanks for testing,

> However, the git binary doesn't detect my motherboard's onboard HDA Intel PCH sound card (like the default pulseaudio in ubuntu does)

This could be because we have removed extra-hdmi.conf. There might still be a udev rule referencing extra-hdmi.conf as this is taken from the system rather from the new PA you're running.

You can work around this by making a symlink from extra-hdmi.conf to default.conf in src/modules/alsa/mixer/profile-sets/

> it only detects the UA-101 and then only the audio outputs, not the audio inputs.

That it only detects the audio inputs is not expected. Could you get a PulseAudio verbose log of this (run pulseaudio with -vvvv )?

[Joe Clifford (joeclifford)]

Thanks David,

The symlink you mentioned fixed the detection of my onboard sound card and with pulseaudio-git it shows SPDIF and Headphones outputs and a Microphone input and they both work as expected. The installed ubuntu pulseaudio also has an Analogue audio output that isn't shown in the gnome audio mixer settings when using pulseaudio-git, though I'm guessing this is either an alias for the onboard Intel 5.1 or perhaps pulseaudio-git has jack insert/removal detection... anyway the sound works through headphones and mic as expected.

I've attached the output of pulseaudio-git when run with -vvvv.

To provide a clean log I first removed ~/.pulse, ~/.pulse-cookie and ~/.config/pulse, then did the following to ensure pulseaudio doesn't autospawn:

mkdir ~/.pulse
echo "autospawn=no" >> ~/.pulse/client.conf
pulseaudio -k
./src/pulseaudio -vvvv --log-target=newfile:pulseaudio.log

Steps taken after running pulseaudio-git are as follows:

1. Wait for pulseaudio to settle then turn on UA-101 with manual switch on the device
2. Wait for pulseaudio to settle then open gnome audio settings
3. Highlight UA-101 in gnome audio settings to make it the default output ("Play sound through")
4. There is a button on the gnome audio settings window that allows me to change from "Multichannel output" to "Multichannel input" - I change this and the UA-101 device disappears from the overview and seemingly with no way to get it back except for deleting anything pulseaudio related from my home directory and restarting pulseaudio.
5. Close gnome audio settings and turn off the UA-101 before killing pulseaudio.

The UA-101 doesn't have any alsa controls at all - nothing is picked up in alsamixer. In Windows, the 10 input and output channels are controlled by a software mixer. I'm wondering if this is why the inputs are not detected by pulseaudio?

[David Henningsson (diwic)]

Thanks for the log. Looking at the log, PulseAudio seems to do the right thing. It first tests input:multichannel, which succeeds, then output:multichannel, which also succeeds, but when then trying full duplex, we get an error back from the kernel:

I: [lt-pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_PREPARE failed (-16)
I: [lt-pulseaudio] alsa-util.c: snd_pcm_hw_params failed: Device or resource busy

As a result, "Multichannel input" and "Multichannel output" are available, but not the combination of both. From your point 4) it sounds like the gnome audio settings react a bit strange/buggy on this. I assume you have checked both "output" and "input" tabs, right? If you change from "Multichannel output" to "Multichannel input" and it disappears on the output tab, it should start showing up on the input tab instead. Otherwise you can use the pavucontrol to change profile (on the configuration tab of pavucontrol).

But the main question is why full duplex fails here - are you getting full duplex to work with other applications (that are not using PulseAudio)?

[Joe Clifford (joeclifford)]

Hi David, Raymond, thanks for your follow up. Here is more pertinent information:

Changing from "Multichannel output" to "Multichannel input" on the Output tab in gnome sound settings makes the UA-101 output device disappear completely and permenantly and it does not appear in the Input tab. The only way to restore it is remove pulse files from home directory or use pavucontrol.

Checking pavucontrol in this instance shows that the profile for the card has actually been set to "Off" rather than "Multichannel Input".

Changing the profile in pavucontrol for the UA-101 to "Multichannel Output" shows a 10 channel output device, set up with 10 channel output device (with 8x 7.1 surround channels and 2 auxs) in the Output Devices tab of pavucontrol and a 10 channel input device called "Monitor of EDIROL UA-101 Multichannel" set up with the same channel names as the outputs in the Input Devices tab.

Changing the configuration profile to "Multichannel Input" and the UA-101 device disappears completely and there are no devices representing the UA-101 in either the Output or Input tabs of pavucontrol.

Using Jack2 and QJackCtl works, creating 12 inputs and 10 outputs. QJackCtl log is as follows:

jackd using same period size for playback and capture , playback and capture start at same time but pulseaudio won't start playback and capture at same tone

[Raymond (superquad-vortex2)]

*
  * Synchronizing the playback rate to the capture rate is done by using
  * the same sequence of packet sizes for both streams.
  * Submitting a playback URB therefore requires both a ready URB and
  * the size of the corresponding capture packet, i.e., both playback
  * and capture URBs must have been completed. Since the USB core does
  * not guarantee that playback and capture complete callbacks are
  * called alternately, we use two FIFOs for packet sizes and read URBs;
  * submitting playback URBs is possible as long as both FIFOs are
  * nonempty.
  */

the driver seem expect same rate for playback and capture

There was a bug with multichannel duplex where the number of output and input channels are different, which should be fixed by:

http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/modules/alsa?id=02dc6d84edde7af86e155b224b6aa98080ef2979

That fix has not been released into Ubuntu yet, though.
