> Package: libasound2
> Version: 1.1.7-1
> Severity: important
> Dear Maintainer,
> Please forgive my lack of familiarity with ALSA.
> I use sox in a script to play an mp3 via STDIN, using the
> AUDIODRIVER=alsa environment variable. Since upgrading libasound2 from
> 1.1.6-1 to 1.1.7-1 this morning, the script now gives the following
> error:
>     ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave
>     play FAIL formats: can’t open output file `default’: snd_pcm_open error: No such file or directory
> I ran speaker-test to try to isolate the problem. The output is below:
>     speaker-test 1.1.6
>     Playback device is default
>     Stream parameters are 48000Hz, S16_LE, 1 channels
>     Using 16 octaves of pink noise
>     ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave
>     Playback open error: -2,No such file or directory
> Sound works throughout the rest of the system – I assume via PulseAudio?
> I’m happy to provide any other information to help diagnose the problem.

libasound2-plugins 1.1.7-2 and alsa-utils 1.1.7-1 should arrive soon
in testing. Please update them first and come back to this bug

Thanks for your patience

  Obviously the human brain works like a computer.
  Since there are no stupid computers humans can't be stupid.
  There are just a few running with Windows or even CE ;-)
