I have a Vortex 2 SQ2500 Gold PCI card connected to a Soekris 4501 embedded MOBO. Pebble linux distro was installed. Kernel was rebuilt with sound support compiled in. Driver 1.1.3 was compiled on a RHL9 machine with a PIII. Target 4501 is a 486. After hacking the make file to target a 486 architecture and changing the include file location for the kernel source (target is running kernel version 2.4.22), driver compiled fine and was installed manually on embedded cf card.
So far, so good. Embedded board recognizes card. Modprobe loads driver. Here is config info...
lspci says this:

Running modprobe au8830 gives this in dmesg:

Output from /dev/sndstat gives this:

So what could possibly be the problem you may ask? No sound!
I have tried a simple 'cat sample.au > /dev/audio' - nada.
I have tried mpg123-oss-i486. It appears to play an mp3. Chews up 40% of the CPU. Verbose output shows frames flying by. No audio.
Made sure aumix has volume turned up.
Anyone have any ideas? I am stuck. Thanks ahead of time.
I know this sounds silly, and I apologise for asking it, but do you have the volume turned up at all?
Yes, I used aumix to turn up all output devices to 100%. Speakers are plugged in and turned on. I know someone had to ask.
As an aside, I upgraded to the 220.127.116.11 drivers to no avail. Everything appears like it should work, but still no sound. I'm pulling my hair out.
I would suggest trying the ALSA driver. It works much better than the OSS driver and supports more features (hardware EQ, SPDIF. more channels).
