I don't _know_ what it is, but I think it is the firefox way to chose a
way of audio output. Since /dev/dsp is from the OSS days it might be
needed to tell firefox to use it directly.

aoss is the user-space OSS emulation of ALSA (IIRC). You could try
"oss". I don't know if this helps.

It could be that the current firefox version doesn't use OSS any more,
it's been some time since I used libaudiooss with firefox. I think it
was firefox version 2.0.0.x...

Another way would be to use arts, tell firefox to use it and configure
arts to use nas. This is ugly as hell and kind of fragile, but it might

Well, I don't have ALSA skills, and to me they seem to be a lot harder
to acquire than OSS skills (which I did not have before working on the
OSS nasd). I'd like to see this functionality in ALSA, but I won't have
the time and motivation to do it myself. :/
