Re: Updated: via8233 driver -- testers wanted

["René Kermis" <kermis@gmx.de>]

I tried to measure the interrupts. Here are the results:

If I don't play sounds, I have about 1 interrupt/sec on interrupt 11.
If I play a mp3 with mpg321 (44,1kHz, 16bit), I get about 1375
interrupts/sec.
All values are measured after initializing the chip with oss-module,
removing it from memory and reloading alsa-module. If I don't load the
oss-module before and remove it, there are no interrupts used.
