[opensuse-kernel] ALSA problems with 2.6.30-rc3-13-vanilla
There is a big difference w.r.t. to volume whether I use mplayer to play, say, a flash audio file or a Adobe's flash player within Firefox. The latter's volume is far too small. Additionally, the flash player, even if not active (but open in a Firefox tab), blocks ALSA somehow: wl@linux-nvf0:~> mplayer xxx.flash MPlayer dev-SVN-r29116-4.3-openSUSE Linux 11.1 (i686)-Packman [...] Playing xxx.flash. libavformat file format detected.

It sounds like a problem with the volume inconsistency between different sound subsystems. Judging from the output above, some (flashplayer, supposedly) seem to be using pulseaudio backend. If you aren't using PA in general, try to uninstall libflashsupport package. Anyway, the issue has basically nothing to do with the kernel :) Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Well, it's even more, unfortunately. After suspending, PulseAudio no longer works: pulseaudio[3841]: module-alsa-sink.c: \ Error opening PCM device front:0: Das Argument ist ungültig pulseaudio[3841]: sink-input.c: \ Assertion 'i->thread_info.rewrite_nbytes == 0' failed at \ pulsecore/sink-input.c:1144, function \ pa_sink_input_request_rewind(). Aborting.
Well, I use KDE 4, and this mandates PulseAudio, AFAIK.
Anyway, the issue has basically nothing to do with the kernel :)
OK. Will contact a PulseAudio list instead. Werner -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Hm, that's bad. Does this happen with the Factory version of PA, 0.9.14?
Really? PA is mandatory for GNOME, but I thought KDE can work without it... Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
Will try. Hopefully, the RPM works on top of openSuSE 11.1...
Honestly, I have no idea :-) At least KDE emits no longer any sound as soon as PulseAudio dies. Maybe it's configurable, I don't know. Werner -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
