gmplayer and mplayer use both the exact same code to handle alsa,
there is no difference there. If one works the other should too...
... unless you have different configs, but then it's clearly PEBCAK.

Me ? Yes. For me the oss emulation always worked better than accessing
alsa directly, no matter what programm i used. (and i use alsa since
the early 0.5 days). Somewhen after 0.9 was out, i stopped carring
whether the alsa interface worked or not as i didn't had the time
to check it on every update. So yes, i use the oss emulation for everything.

Yes, that's true and i'm sorry for that. But output modules have
to be written by people who understand them. If none of the developers
care, none will improve it unless we get some patches.
And ao_alsa.c being with 1174 lines the bigges ao module doesn't
make it easier.

So, feel free to send us suggestions, patches, whatever to make
the alsa output better. We'd appreciate it.
