Description atrus 2001-05-27 19:10:00 UTC

WHen using XMMS to play on a AC97 board via. the PCM driver (pcm0: <VIA VT82C686A> port 0xd400-0xd403,0xd000-0xd003,0xcc00-0xccff irq 9 at device 7.5 on pci0 ), playback is too fast. I suspect something isn't right with the sample rates.

Fix: 

Better implementation of sample rates?
How-To-Repeat: Use a standard playback utility with the PCM driver on that board.

Apparently I'm now the maintainer of this driver since I acquired a board...

Your card is locked at 48KHz. xmms detects this error and blindly continues 
playing sound. The current driver doesn't support any resampling (either in 
software or as a function of the card), but a rate feeder is in development 
for -CURRENT.
