I have a strange request (which is why I'm sending directly to the dev list). I'm trying to run Flash video (v9 or v10) on Firefox 3 on a Fedora 8 image running on Amazon EC2. I don't actually want/need sound (it's of course technically not possible, since EC2 doesn't provide a sound card). Video playback (when watched through VNC) goes fine for a couple minutes, but then the browser and flash lock up entirely. I've looked for ways to tell Firefox and/or Flash to not send audio out, but I've come up empty so far. So now I'm hoping that fixing this error and putting in perhaps some sort of "no op" device might help out.
I'm not positive the error is related to ALSA, though the fact that there appear to be a ton of the following logs just before the lockup is suspicious:
ALSA lib confmisc.c:768:(parse_card) cannot find card '0' ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default ALSA lib pcm_hw.c:1240:(_snd_pcm_hw_open) Invalid value for card
(these lines repeat over and over again until the crash happens, then it stops promptly)
As you can see by the alsa-info output at the following URL, I don't have any running snd modules:

Similarly, I don't have any sound-related devices installed (ie: /dev/audio, etc). My hope in emailing this list is that there may be a solution that causes ALSA to no-op the requests that Firefox/Flash send it's way, potentially solving the lockup I'm experiencing.
I would really appreciate any ideas that could be shared. Thank you very much!
