Still maximum period size is 512, just as before.
Try start alsaplayer:
alsaplayer -f 2048
alsaplayer -f 1024
alsaplayer -f 512
alsaplayer -f 128
alsaplayer -f 64
And you can try start jackd:
/usr/local/bin/jackd -R -a -d alsa -p 512 -d pcm.cs46xx
/usr/local/bin/jackd -R -a -d alsa -p 128 -d pcm.cs46xx
/usr/local/bin/jackd -R -a -d alsa -p 64 -d pcm.cs46xx
/usr/local/bin/jackd -R -a -d alsa -p 32 -d pcm.cs46xx
Should work OK, however you probably wil have a lot of xruns
with low period sizes.
Should be interesting test this with low-latency patch, or
preemptive-scheduler.
