Hello all,
it was quite busy month for the ALSA development. The 1.0.3
packages were released. I would like to note that most of problems with
rate resampling plugin were solved (thus indirectly the most of dmix
issues, too). Also, aoss wrapper code (alsa-oss package) was recoded
and improved.
Two new drivers were added: HDSP MADI and snd-atiixp for ATI
chips.
If you reported a bug, please, check, if this new code solves your
problem and write the actual situation to your bug-report. Thanks.
Enjoy new ALSA,
Jaroslav

the directory used for socket files of direct pcm plugins

-fPIC libraries
- rate plugin
- redesigned; now only whole periods are resampled to
avoid rounding problems and to allow using other "block" algorithms
- jack plugin
- this patch changes the JACK plugin to use a unique client name, which
allows for multiple ALSA streams to share a JACK server
