This error message can only occur when using the alsa output module, as the error message is in modules/audio_output/alsa.c. This exact error message is part of the following upstream change: From: Rémi Denis-Courmont <r...@remlab.net> Date: Wed, 21 Apr 2010 17:37:07 +0000 (+0300) Subject: ALSA: give a clue that VLC might fail with alsa-lib <= 1.0.23...

I very well imagine that this happens only on specific hardware and vlc upstream claims it to be fixed in current alsa-lib development and can be easily avoided by using pulse instead. I consider this good advice! I propose to reassign this issue to the libasound2 package and ask its maintainers to have a look at it. -- Gruesse/greetings, Reinhard Tartler, KeyID 945348A4 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
