[VIA VT1702] Recording problem / Sound Recorder does not pick up sound

[Aaron Long]

Sound Recorder doesn't record. I can't get internal microphone up on my gateway laptop after trying all the modprobe.d/alsa-base.conf on the forums, plus dozens of other suggestions. Any help would be appreciated greatly!

[Daniel T Chen (crimsun)]

Please see https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules.

[Aaron Long (planetlong)]

Thanks for the reply Daniel. ppa was added and update performed. sudo apt-get install linux-alsa-driver-modules-$(uname -r)
returns: E: Couldn't find package linux-alsa-driver-modules-2.6.32-26-generic. uname -r returns: 2.6.32-26-generic. Still no mic after reboot. also just tried linux-backports-modules-alsa-lucid-generic with no joy. Any other suggestions?

[Aaron Long (planetlong)]

FYI linux-backports-modules-alsa-lucid-generic made sound recorder feed null. Error came back after test record saying: no stream available, so I pulled backports out. Sound recorder now acts as it did before: shows recording, with very little [constant] level, then playback is low level static. I have checked all levels in alsamixer and pavucontrol. System is acting the same as when bug was reported.

[Daniel T Chen (crimsun)]

What about linux-alsa-driver-modules from the Audio wiki page?

[Aaron Long (planetlong)]

ppa was added and update performed. sudo apt-get install linux-alsa-driver-modules-$(uname -r)
returns: E: Couldn't find package linux-alsa-driver-modules-2.6.32-26-generic. uname -r returns: 2.6.32-26-generic.

[Daniel T Chen (crimsun)]

Can you try again when running 2.6.32-25-generic?

[Aaron Long (planetlong)]

Followed wiki page after booting 2.6.32-25-generic. Installation of linux-alsa-driver-modules-$(uname -r) 2.6.32-25 was successful. Interestingly, sound recorder then acted like it did at 2.6.32-26 with backports installed eg. sound recorder feed null. Error comes back after test record saying: no data in stream. Also, had selection in sound preferences and pavucontrol for mic 1 and 2. Now with 2.6.32-25 and linux-alsa-driver-modules installed this mic selection is gone.

[Daniel T Chen (crimsun)]

Please attach the output from the following commands while using 2.6.32-25-generic with linux-alsa-driver-modules:

pactl stat
amixer

Mic selection is automatic in the newer drivers based on the presence (jack detection) of an external mic being inserted or removed.

Also, just discovered headphone jack is down in current config.

Scratch the last comment... headphone jack IS working, but NOT muting onboard speakers.

Can you follow https://wiki.ubuntu.com/Audio/AlsaInfo while using the latest
daily build (after updating as necessary) of the sound drivers?

This was done in 2.6.32-26-generic (wasn't sure if you wanted me in 2.6.32-25) I upgraded alsa drivers by following http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/ and alsa is now at .23 -- cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on Dec 2 2010 for kernel 2.6.32-26-generic (SMP).

Sound recorder returns: "stream contains no data" ; tried both mic 1 & 2, no movement on level meter.
Jack sense is broken and/or no audio through headphones after this upgrade.

Thx again for the help!

[Raymond (superquad-vortex2)]

The internal mic is at node 0x1e and it has no connection to Node 0x13 [Audio selector] connected to [Audio Input] 0x12

Node 0x1e is connected to Node 0x1f [Audio Input] , so you may need to use hw:0,0,1

[Raymond (superquad-vortex2)]

There is problem if the driver group the three [Audio Input] 0x1f , 0x12 and 0x20 in the same device since node 0x1f support 16bits 16000Hz and 32000 Hz but not 20bit , 24bit or 19200Hz as the other node 0x12 and 0x20

The driver just query node 0x12 instead of 0x1f for the formats and rates

[Aaron Long (planetlong)]

If I understand, you want me to direct the driver to "query node 0x12 instead of 0x1f for the formats and rates"

Forgive me, I'm a bit lost on how to do that. Any suggestions or commands would be appreciated!

[Raymond (superquad-vortex2)]

>> arecord: pcm_read:1692: read error: Input/output error

you have to ask the alsa developer for this issue since 44100 Hz , 16bits and 2 channels is still supported by 0x1f , 0x12 and 0x20, I have no idea why

However many users expect they can use the internal mic by default

>> Headset jack has audio. Jack sense does not mute speakers.

the inactive controls are grey in color if you are using alsamixer

or compare the output of amixer and "amixer -i"

amixer -h

Available options

The point is only spec->adc_nids[0] is used in via_build_pcms

1953 static int via_build_pcms(struct hda_codec *codec)
1954 {
1955 struct via_spec *spec = codec->spec;
1956 struct hda_pcm *info = spec->pcm_rec;
1957
1958 codec->num_pcms = 1;
1959 codec->pcm_info = info;
1960
1961 info->name = spec->stream_name_analog;
1962 info->stream[SNDRV_PCM_STREAM_PLAYBACK] =
1963 *(spec->stream_analog_playback);
1964 info->stream[SNDRV_PCM_STREAM_PLAYBACK].nid =
1965 spec->multiout.dac_nids[0];
1966 info->stream[SNDRV_PCM_STREAM_CAPTURE] = *(spec->stream_analog_capture);
1967 info->stream[SNDRV_PCM_STREAM_CAPTURE].nid = spec->adc_nids[0];

Thanks for all the help Raymond! I've tried to reach out to the ALSA development team, but have been unsuccessful in finding the right route.

Could you direct me to the person/s that you think may be able to help?

[xteejx (xteejx-deactivatedaccount)]

Hi Aaron,
I didn't see that you already had but I may have missed it. Could you please test this issue with the live environment of the Desktop CD of the development release - Natty Narwhal. You can find out more about the development release at http://www.ubuntu.com/testing/. Once tested, this bug can then be sent upstream to the ALSA developers (https://bugtrack.alsa-project.org) for them to take a look at. Thanks again and we appreciate your help.

[Aaron Long (planetlong)]

Thanks for the suggestion Teej,

I hadn't tried Natty Narwhal yet. I booted Alpha 3 and tested sound recorder with no joy. Should I post any specific outputs? "arecord -v -Dhw:0,0,2 -f cd test.wav" did throw a different error...

[xteejx (xteejx-deactivatedaccount)]

Hmm, pcm read error seems to suggest that Ubuntu cannot grab the sound card, possibly because of a driver problem. I have assigned it to the linux package and will subscribe the Audio Team.

[xteejx (xteejx-deactivatedaccount)]

If you have already been given this link please ignore it, if not could you run through all steps on the troubleshooting page at https://help.ubuntu.com/community/SoundTroubleshootingProcedure and attach any output as separate files (not paste as it looks messy). Thank you again.

[xteejx (xteejx-deactivatedaccount)]

Note: Where it says open/post a question, don't. Just add it here as an attachment. Thank you.

Here's some natty alsa-info also..

Thanks for checking it out, I appreciate the help!

[xteejx (xteejx-deactivatedaccount)]

Hi Aaron,
Thank you for those bits of information. I have sent this upstream to the ALSA developers where they will now take charge of it. You can track their progress and make comments (and provide more info if they need it) at https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5322 . Bug watch added.
Thank you again for reporting this to us and helping to make Ubuntu better, and for the quick replies.

[penalvch (penalvch)]

Aaron Long, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
