Cannot record using alsa + gstreamer framework

Thanks for your bug. When do you get those messages? When starting the application or when trying to play a sound? What soundcard do you have?

Martin any idea on that?

Sound Recorder refuses to do any recording, period. This error is trying to test the ALSA input pipeline through gstreamer-properties.

Fixed; stupid asound.conf software mixing!

Can you please explain this a bit? Is it something you changed
locally, which broke gstreamer? Or does Ubuntu provide a wrong
default?

Thank you,

Martin

I can confirm this on my system too

$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
                     HDA Intel at 0xffa3c000 irq 169

gstreamer-properties:
I try to test alsa input source, and it fails with the message that it was unable to construct the pipeline.

I haven't tweaked any asound.conf's

It was my fault; I set up /etc/asound.conf with software mixing, which
apparently broke recording. The default Ubuntu configuration works fine.

Sorry about the trouble.

Alright, then I guess we can close this bug.

 status rejected

No worries, thanks for your help with resolving this.

Should I open a new report or reopen this :( Seems that you missed my comment

Sorry, Vytas, I didn't see it. I just reopen this bug, no need to create a new one.

part of
GST_DEBUG=3 gstreamer-properties

when I try to test input sink

This is serious problem. First of all, I can't record anything with GNOME Sound Recorder now (I got filled one bug about similar problem some time ago #30434) with newest Dapper upgrades. I can record though with arecord: arecord --device default -f cd tests.wav.
But 'gst-launch-0.10 alsasrc device=default ! flacenc ! filesink location=test.flac' creates just file, but writes nothing in it, t.i. it keeps size zero. Even default doesn't work. However, using audiotestsrc instead of alsasrc works, so problem seems to be in gstreamer-alsa plugin, especially in alsasrc.

I am also experiencing this bug, and I see it as a serious problem. It basically blocks the ability to record audio on many laptops.

I filed a bug against GStreamer on the GNOME bugzilla and I included plenty of debugging information.

See http://bugzilla.gnome.org/show_bug.cgi?id=336614

  Jono

This is pipeline debugging with:

export GST_DEBUG=*:5
export GST_DEBUG_NO_COLOR=1
gst-launch-0.10 alsasrc device=default ! flacenc ! filesink location=flac.flac

Last lines I could grab it. Most interesting part IMHO is

Would those of you experiencing this bug please attach output from ``tail -2 /proc/asound/oss/sndstat''?

result of 'trail -2 /proc/asound/oss/sndstat':

2: Realtek ALC650E

I have two cards (lspci):

$ cat /proc/asound/pcm

To provide some debugging info, I did this:

export GST_DEBUG=*:5
export GST_DEBUG_NO_COLOR=1
gnome-sound-recorder noinput.txt 2>&1

SAME FOR ME. Doesn't work. I'm trying on a note pc. Panasonic Cf-Y4.
Here are the test i tried.
Launching from console gstreamer-properties
I receive:
gstreamer-properties-Message: Skipping unavailable plugin 'artsdsink'
gstreamer-properties-Message: Skipping unavailable plugin 'polypsink'
gstreamer-properties-Message: Skipping unavailable plugin 'sdlvideosink'
gstreamer-properties-Message: Skipping unavailable plugin 'v4lmjpegsrc'

gstreamer-properties-Message: Skipping unavailable plugin 'v4l2src'
gstreamer-properties-Message: Skipping unavailable plugin 'esdmon'
gstreamer-properties-Message: Skipping unavailable plugin 'polypsrc'

Audio output works but If I select
both alsa (alsasrc) or oss (osssrc) I receive n error message that the test pipeline cannot be created.

I don't quite understand the meaning of the test above, however

gst-launch-0.10 alsasrc device=default ! flacenc ! filesink location=flac.flac

produce:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

i juist recocmpiled gst-plugins-base0.10-0.10.5 without
10_audiosink-lockup.patch
and it works again...

adds another change from cvs to make alsasrc work again.

Thank you for the patch, that upload fixes the issue:

 gst-plugins-base0.10 (0.10.5-0ubuntu3) dapper; urgency=low
 .
   * debian/patches/10_audiosink-lockup.patch:
     - patch update by j^ <email address hidden>, fix alsasrc (Ubuntu: #34597, #35733)

I can confirm that it works now. Thanks j^ for fixing and everyone for debug info.

Likewise. Works fine here now. Thanks! :)
