Red Hat Bugzilla – Bug 120540
alsasink fails with error in pcm_plug.c with snd_via82xx soundcard
Last modified: 2007-11-30 17:10:40 EST
Description of problem:
When trying to use the alsasink to play audio it fails consistently.
Using osssink and alsa's oss emulation layer works however.
Version-Release number of selected component (if applicable):
gstreamer-0.8.0-4 (from core/development)
[noa@marit slask]$ uname -r
Steps to Reproduce:
1. set up a gstreamer pipeline with the following command:
gst-launch-0.8 filesrc location="/usr/share/sounds/startup3.wav" !
wavparse ! alsasink
gst-launch-0.8: pcm_plug.c:882: snd_pcm_plug_hw_params: Assertion `err
>= 0' failed.
something similiar to the result when replacing alsasink above with
as an additional datapoint ogg123 from vorbis-tools-1.0.1-2 seems to
be able to successfully use alsa output
The upstream bug is http://bugzilla.gnome.org/show_bug.cgi?id=134007
who in turn references an alsa bug at
It seems like the problem is hardware specific to my soundcard,
identified by lspci as
00:11.5 Multimedia audio controller: VIA Technologies, Inc.
VT8233/A/8235/8237 AC97 Audio Controller (rev 50)
Unfortunately the alsa bugtracker seems broken so I can't sign up.
