[Bug 321028] Re: 8.10 - avidemux - trouble initializing audio device

[André Pirard]

ALSA _does_ work for Avidemux 2.4.3 on Ubuntu 8.10.
But the problem is that Avidemux/Edit/Preferences/Audio/ALSA device is set to "dmix" by default.
Setting it to "default" solves the "trouble initializing" etc... problems.

dmix is an ALSA plugin.
Should it always be enabled and Avidemux is not to blame?
Or should Avidemux not assume dmix is enabled and use the system's default?
Or should it try to use dmix and revert to "default", with or without user's consent?
I don't know,.
But if it took 3 months for launchpad to determine this, I know that the general user is even more clueless and I would certainly call that a bug.
I don't know where, I leave that up to the integrator, but that's somewhere.


** Changed in: avidemux (Ubuntu)
       Status: Invalid => New

** Description changed:

  Binary package hint: avidemux
  
  Running Avidemux (installed using apt-get) and trying to play any of the video gives the error:
  Trouble initializing audio device
  
  running from command line and doing it gives this error:

  [Bridge] Starting with time 2127, shift 0

  Error opening PCM device dmix
  ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave
  Error opening PCM device dmix
  
  steps to reproduce:
  1) Install avidemux
  2) open any video with it
  3) try to play the video in the program, it can't play the audio.
  
  Audio plays fine in all other applications.
