[Bug 475355] Re: Choppy sound on Vortex 2 under Karmic

[Raymond]

Refer to log in #13

I: alsa-sink.c: Using 16.0 fragments of size 4096 bytes (23.22ms), buffer size is 65536 bytes (371.52ms)
I: alsa-sink.c: Time scheduling watermark is 20.00ms

watermark 20ms is not enough since au88x0 has 4 hardware subbuffers

you cannot let PA sleep 348ms and wakeup 20.00ms before the buffer is
empty, most likely PA have to wakeup 69ms when there is about  3 periods
left in the buffer

can you increase initial watermark to 69ms when using 16 period x
period_size 1024  ?

or try using 2 fragments of size 4096 bytes which work quite well in
Fedora 10 using PA 0.9.13
