Hi. I have Red Hat 7.2 and have an Aureal Vortex 1 card.
I've installed the au8820 driver for the card, which I know is the correct one, but I get almost no sound.

I have managed to get sound only when running mozilla. I went to an e-card site and it started playing sound (albeit bad sound).
All other types of sound do not work including xmms with mp3 and wav, even the CD player won't play.

Here's what varlog says.

au88xx: Loading...
PCI: Found IRQ 11 for device 00:0c.0
au88xx: Found vortex PCI device
au88xx: id=0x0001
au88xx: bar0=0xdf800000
au88xx: irq=11
au88xx: mem 0xdf800000-0Xdf83ffff in use
au88xx: Add device, audio=3, mixer=0, midi=2
Journalled Block Device driver loaded

Do I need to chanage irq or memory it uses? How do I do this?
Also, my modules.conf says

options sound dmabuf=1
alias synth0 op13
options op13 io=0x388

Help!!

Welcome to LQ. Not being daft, and I don't mean to be rude, but check your volume levels. There have been quite a few posts of a similar nature when the only problem was that they hadn't turned the volume up. Check back here if you still have problems.
