Hi,
now I'm stabilizing the driver a bit. I hope it won't hang up any more (so often), and make you happy testing.
speakers-test and aplay works perfect with both base_rates and any sample rate (tried only stereo samples), but mplayer become more glitchy
- sound pauses for a bit every 5-10 seconds, dmesg included.
- As default, the driver works only as a constant sample rate, either 48000 or 96000 (default). The rate can be changed via the module option base_rate. For enabling the continuous rate support (it was on before), define XXX_CONT_RATE in sbxfi.c.
only tried speakers-test: 96khz works fine 48khz plays slow (frequency is lower than it should be) 44.1khz silent, speakers-test ends with error, dmesg included.

- If playback works well, try to define XXX_USE_SG in sbxfi.c. This will make the driver using SG buffer instead of continuous pages.
works absolutely the same as without it.
- Also, test SBXFI_DMA_MASK being DMA_32BIT_MASK, especially if you have RAM more than 2GB.
i have 3GB RAM on my test box, everything worked fine with 32-bit mask, but i haven't done many tests...
- You can try dmix as well. E.g. simply run like % aplay -Dplug:dmix:0 foo.wav
works fine.

I tested several players with alsa (oss causes oops): xine works fine xmms ok mplayer constantly shows some error message I wasn't able to read (it's blinking) and sound pauses for ~0.2 second every ~27 seconds.
