I sure remember struggling with flash audio issues over the years! While I am clueless to offer additional hints on possible solutions, I do have a trusty workaround for many (not all) flash renditions and confess to using this regularly for playback navigation and speed control: Pause playback in flashplayer. The file will continue to download. Launch mplayer, play the file. Enjoy the movie. ralph(a)spike ~$ cd /tmp;ls |grep Flash |xargs mplayer Regards and good luck, Ralph P.S.

I've found that sometimes gnome-alsamixer has channels/options that regular alsamixer does not have.

The "-f" should take care of that. I use iceweasel 3.6.4 (from experimental), too, so we can compare: The first difference that I notice is that after reading your ~/.asoundrc, no further configuration is taken into account: 3470 access("/home/ron/.asoundrc", R_OK) = 0 3470 open("/home/ron/.asoundrc", O_RDONLY) = 17 3470 open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = 17 In my case, without ~/.asoundrc, more configuration files are read: 6066 access("/home/florian/.asoundrc", R_OK) = -1 ENOENT (No such file or directory) 6066 open("/usr/share/alsa/cards/aliases.conf", O_RDONLY) = 17 6066 open("/usr/share/alsa/pcm/default.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/dmix.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/dsnoop.conf", O_RDONLY) = 18 6066 open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = 17 Maybe you should try to include these other configuration files in your ~/.asoundrc. I would also be tempted to test the effect of temporarily removing your ~/.asoundrc. (You already said that this breaks all other sound, but what does it do to flashplayer?) After that, your flashplayer repeats this over and over: 3470 open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = 17 3470 open("/dev/snd/controlC0", O_RDWR|O_CLOEXEC) = 17 3470 open("/dev/snd/controlC0", O_RDWR|O_CLOEXEC) = 17 3470 open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK|O_CLOEXEC) = 18 3470 stat64("/usr/share/alsa/alsa.conf", {st_mode=S_IFREG|0644, st_size=8967, ...}) = 0 In my case, it opens some chipset-specific configuration files: 6066 open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = 17 6066 stat64("/usr/share/alsa/alsa.conf", {st_mode=S_IFREG|0644, st_size=8967, ...}) = 0 6066 open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = 17 6066 open("/dev/snd/controlC0", O_RDWR|O_CLOEXEC) = 17 6066 access("/usr/share/alsa/cards/ICH4.conf", R_OK) = 0 6066 open("/usr/share/alsa/cards/ICH4.conf", O_RDONLY) = 17 6066 open("/usr/share/alsa/pcm/front.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/surround40.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/surround41.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/surround50.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/surround51.conf", O_RDONLY) = 18 6066 open("/usr/share/alsa/pcm/iec958.conf", O_RDONLY) = 18 Then my flashplayer tries to open all other controls (controlCxx), probably to check for further soundcards, and finally it accesses controlC0, pcmC0D0p and timer. It seems that your flashplayer does access the correct device and there are no indications of problems with permissions or lockout by another process, but it just does not know how to configure and use your hardware properly.

My strace was from using flashplayer-mozilla, so maybe it is time to give it another try. I am not too optimistic, though; the player seems to have a fundamental problem with the configuration of your hardware. -- Regards, | Florian | -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
