[Hardy] Roland Edirol UA-101 not supported anymore

[Janek]

Binary package hint: pulseaudio

Since Ubuntu 7.10 Gutsy my Sound Interface from Roland, Edirol UA-101 worked perfectly - with jack I was able to connect all audio ports together but also simple sound output with alsa and ESD was no problem. But now in Hardy beta my I can't get sound output working and my card isn't shown in "System/Preferences/Sound". But alsa still detects it - that's why I think it has something todo with pulseaudio. How can I enable pulseaudio to work with my soundcard?

~$ asoundconf list
Names of available sound cards:
UA101

Okay I have some more information:

When I manually restart pulseaudio and look at the terminal output it looks like that:

$ pulseaudio

It looks like PulseAudio tries to use the card detected by alsa but there is an error - But I don't know why...

Okay after reading this again I have an idea what the problem is:

PulseAudio needs a mixer control like "PCM" or "Master" but alsa does not support software mixers for my card. That's not a problem for me I can use my external mixer but pulseaudio does not like that... What a crap ;) I'm going to ask in the PulseAudio IRC.

The output of pulseaudio again with -vvv in attachement

[Luke Yelavich (themuso)]

Could you possibly attach a list of the mixer controls for your card? The amixer command is useful to obtain these.

[Janek (thefoxx)]

Would be nice to have this but I get nothing when running amixer:

$ amixer
$

I think there arent any software mixer controls available for this card. For example on Windows the Windows mixer does not work as well - There I have to use the mixer which is on the driver CD.

My soundcard is terratec DMX6Fire. Alsa does not support software mixers for my card too.
Same problem occurs in pulseaudio.

I also have a DMX6Fire (ice1712) as YB hendrick.

I was able to make my own channel mapping in /etc/pulse/default.pa which remedied the problem. Here's a link to a pulseaudio discussion list which explains it: https://tango.0pointer.de/pipermail/pulseaudio-discuss/2008-January/001240.html

[YB hendrick (youngeye)]

I appreciate your help!!!

Can you tell me your channel mapping for surround setup?

[unlotto (unlotto)]

Just to clarify, the mapping at the link (for Delta 44) is valid for DMX6fire aswell. You can use that.
as the page says:

in /etc/pulse/default.pa comment out module-hal-detect and module-detect and then append lines similar to this:

# Load Dmx:
load-module module-alsa-sink sink_name=dmx_out device=hw:0 channels=10 channel_map=left,right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7
load-module module-alsa-source source_name=dmx_in device=hw:0 channels=12 channel_map=left,right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7,aux8,aux9

# Set the default sink and source
set-default-sink dmx_out
set-default-source dmx_in

Test by running pulseaudio manually.
I would suspect this to work for Roland Edirol UA-101 aswell, based on the fact that all ice1712 chipsets seem to have the same number of channels regardless actual connections.
Notice that my card is hw:0 and not hw:1, because i have disabled the onboard soundcard.

If you wish you may want to create a forum post on the ubuntu forum, as not to go too "offtopic" from this bug report.

[Janek (thefoxx)]

Thank you, it works now!
But now my onboard card isn't detected anymore - I think because the hal-detect modules aren't loaded. I use it for my headset because it allows micro boost and it works if I disconnect my external card too. Is there a way to get hal detect working and using the manual settings simultaneously?
