Description of problem:

Hardware is an MAudio Revolution 7.1 using the ice1724 driver.

aplay produces errors unless I boot with the acpi=off kernel option.  However, even with this option I get no sound output.  I've checked the mixer and changed the volume still nothing.  There are similar bugs like this logged against FC.

Have you updated to the most recent available BIOS version available for your 
motherboard?  If not, please do so and post the results of using sound after 
the upgrade.  Thanks!

This is a relatively old system.  The last BIOS update was in 2001.

The solution was (relatively) simple.  The sound card was sharing an IRQ with my
ethernet card.  I swapped PCI slots and re-enabled ACPI and sound now works as
it should.

It doesn't seem like a shared IRQ should completely prevent playing audio, so I
don't know if this is a bug or a limitation of ALSA.

Comment 4 John W. Linville 2006-02-03 17:15:33 UTC

ACPI support in machines of that vintage is notoriously buggy.  If your system 
works now (or with ACPI disabled), that is probably the best we can do. 
 
I'm glad you got it working!
