ES1969 sound card issues on IBM 390X Thinkpad
Hey all,
Firstly, I better start this off with admitting that I am a newbie to dealing with Linux hardware issues.
I have a stickler of a problem. I am currently running Slackware 9.1 on an IBM 390X Thinkpad, and just recently my sound card has begun acting up. I have an ES1969 card (ESS Solo 1), which is supposed to be supported by Alsa and OSS. Neither seem to work, as I have tried multiple versions of each. The only output I get is a distorted, rumbling sound.
Here's the catch: recently I've upgraded my 390X to feature a 12 gig hard drive, which has replaced my 3.25 gig drive. The new drive is a Travel Star, from IBM, just like the old one. As I was doing so, I figured I might as well upgrade my BIOS firmware to the most recent version offered by IBM (0.55, issued 11/30/99, with the code of ISB055WW), as I was having issues with my CD-ROM losing interrupts on boot-up once I had installed the new HD. Before I made these changes, my ES1969 worked well in Linux.
I don't recall what firmware version I was running prior to making these changes, as this is a new-to-me computer, and I wasn't wise enough to write it down. I also can't find that listed anywhere.
I decided to test my card in Knoppix 3.3. It used to work in that environment, but since those changes were made... no go.
I have not found any drivers that support the ES1969 exclusively. The closest I've gotten is the ES1938 or the ES1942.
I guess my question is: could this issue be caused with a conflicting (or shared IRQ)? I noticed in my new BIOS that 3 of the 4 available PCI components share the same IRQ. Or is it a firmware issue? The sound card seems to work in Windows '98, even with the change.
Anyone have any ideas? I'd really really appreciate them, as this problem has been driving me nuts.
