Before I begin, let me state that I am not a driver-coding guru developer (I wish I was/could be), but I am a long time Linux user and sys admin who generally is able to figure out what needs to be done to get things working. Except this time... To begin, I've got a two year old box with an Asus P5B Deluxe mainboard with the dreaded Intel "High Definition Audio" (HDA) featuring the ADI 1998B codec chip. When I first built the system I simply disabled the onboard sound in the BIOS since I was aware that ALSA development hadn't caught up with that chip yet. But recently I decided to see if I could try to configure the onboard sound to work...and it does, but _only_ the two _front_ channels. My troubles lie in the fact that the front speakers reproduce mid/high range frequencies only and I rely on a subwoofer for the low end and that is not working. In fact, I cannot get any channels other than the front channels to create any output. (This I methodically tested by plugging the speakers into each jack and running something like: speaker-test --channels 8 (blah, blah...) which cycles through all the channels using a sine wave. I have confirmed that all the hardware are fine by booting into the WinXP partition, installing the "SoundMAX" drivers and satellite speakers and subwoofer work great. I just cannot get ALSA to give me any sound out of any channels other than the two front channels. :( Here is an alsa-info.txt using the stock FC8 ALSA rpms: http://www.alsa-project.org/db/?f=a22f8dfb12f5dc8869e9b0e6a0fd758652838210 I also downloaded, compiled and installed the most recent ALSA 1.0.19 driver, libs and utils with the same results: front channels only. I've googled all over everything, searched the alsa.users and alsa.devel mailing lists, read all the docs, even looked over some of the source code for clues and I am stymied. I haven't come across any posts by others describing my situation, so I'm beginning to think this could be just a simple configuration issue that I've missed. (Either that or ALSA still hasn't caught up with this chip yet, but from what I've seen/read I don't believe that is the case.) This has to be a simple configuration issue. Or maybe not so simple: maybe I need to craft a fancy, complicated .asoundrc file? I don't know... Actually, I moved my existing .asoundrc out of the way and replaced it with a simple one. Later, I moved it completely out of the way (i.e., no .asoundrc). Presence/absence of .asoundrc had no effect. I _rarely_ ever post _anywhere_ asking for help, but this time I am stymied, frustrated and desparate. To give you an idea, you wouldn't imagine the relief I felt last night when I booted Windows and it worked. That was a desparate last resort after working on this problem for the past few weeks. Good Lord, you know I had to be desparate to try that! ;) Anyway, thanks for listening and I will definitely appreciate any feedback.
