Try this: http://www.macewan.org/2006/06/01/howto-firefox-flash-video-sound-on-ubuntu-linux-dapper/ IIRC, I had this problem on an old Linux install I was using for MythTV, and it did come down to a lack of OSS support with the installed ALSA.

Uh? No, there are many reports about flash outputing sound to the wrong audio device, even using PA: http://forum.sabayon.org/viewtopic.php?f=56&t=18983 It's even documented in Ubuntu wiki: https://wiki.ubuntu.com/PulseAudio#Firefox/Flash%20and%20PulseAudio >> Maybe is not just Flash the only app having no sound in Iceweasel. >> >> > MP3s play just fine. Then the problem is just affecting flash plugin within Iceweasel. I'd follow the suggestions made by Florian. Mmm... have you tested with another browser (i.e., Epiphany, Konqueror...)?

On my Sid systems it is not bothered at all by the fact that kmix has /dev/snd/controlC0 open, it simply uses /dev/snd/pcmC0D0p and /dev/snd/timer as needed. You could run iceweasel under strace: strace -f -efile -o iceweasel-flash.strace iceweasel Let a flash video play silently for a few seconds and then close the browser. Afterwards you can check what has been accessed: grep -E 'a(lsa|sound)|/dev/(a?dsp|audio|mixer|snd)' iceweasel-flash.strace Before you break out the big guns, though, you can try to set ICEWEASEL_DSP to "aoss" (assuming you have "oss-compat" installed), or maybe installing flashplugin-nonfree-extrasound will help, or switching from flashplugin-nonfree to flashplayer-mozilla, or vice versa. (I did not read the entire thread, maybe some of these things were already suggested.) -- Regards, | Florian | -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
