alsasink results in cracking basses

[Kjell Braden]

Running a command like the following or Quodlibet results in very annoying cracks in the basses.

gst-launch-0.10 filesrc location=/some-stupid-non-free-codec-file.mp3 ! mad ! audioconvert ! audioresample ! alsasink

Playing it via mplayer or the following gstreamer command doesn't:
gst-launch-0.10 filesrc location=/some-stupid-non-free-codec-file.mp3 ! mad ! audioconvert ! audioresample ! osssink

I'm running hardy with gstreamer0.10-alsa 0.10.15-1ubuntu1 installed. Output of "GST_DEBUG_NO_COLOR=1 GST_DEBUG=3 gst-launch-0.10 filesrc location=/some-stupid-non-free-codec-file.mp3 ! mad ! audioconvert ! audioresample ! alsasink" is attached.

I decoded the file with

$ mplayer -ao pcm:fast:waveheader:file=stupid-file.wav some-stupid-non-free-codec-file.mp3

and reencoded it with

$ oggenc stupid-file.wav

Now
$ gst-launch-0.10 filesrc location=stupid-file.wav ! audioconvert ! audioresample ! alsasink
does *NOT* produce the cracking sounds, while
$ gst-launch-0.10 filesrc location=stupid-file.ogg ! audioconvert ! audioresample ! alsasink
does!

Oops, the commands I ran were:

gst-launch-0.10 filesrc location=ew.wav ! decodebin ! audioconvert ! audioresample ! alsasink
and
gst-launch-0.10 filesrc location=ew.ogg ! decodebin ! audioconvert ! audioresample ! alsasink

Hi,
this is a bug in alsa-lib actually... see the patch in http://bugs.debian.org/437827

[Kjell Braden (afflux)]

Right, the patch attached there works.

Should this bug be a duplicate of bug #116990 then? Should it be reopened on alsa-lib?

Hi,

It should be a duplicate of #116990, yes.

 duplicate 116990
