Hi again:

I did a fresh checkout of the latest cvs and replaced the
resulting snd-au8830.o binary from its compile:
Faster playback issue is definately there (it is
like 10% faster than when usin oss-emulation but if
one compares the playbacks it is noticable).
The static-like clicks are also there.
Can someone else with a Vortex2 (an MX300, preferably)
please test this? (Play something in xmms+oss plugin;
stop it and change the ao-plugin to alsa and play again).


Best regards;
Özkan Sezer


BTW: Why is the alsa/sound directory present in the cvs?
Is that not supposed to be a symlink to alsa/alsa-kernel ?
And the former is missing some files compared to the latter?
