Ok. Last night I installed a fresh copy of R5D1 rather than upgrading my R5C7. Before the install process, I disabled the onboard sound (VIA) and hoped it would autodetect my add-on turtle beach card (previously working with R5C7). After reboot, creating the LVM myth volume, I decided to set up my audio. 'alsamixer' shows only the VIA8237 sound card. Now I thought this was a bit strange, as it was disabled in BIOS. So I su'd to root, and fired up alsaconf, and there was my Turtle beach card, as well as the on board(previously disabled) sound card. So I figured, I'll just configure the add on card, like before, and continue on. As soon as I did this, alsamixer showed no available sound cards.

I figured then it must be an alsa 1.0.12rc1 driver thing. So I went out and ftp's the appropriate driver, lib, and utils files from alsa, for 1.0.11 which is what I was using with R5C7. During the make process, it failed, so now I am stuck with no digital sound, and a disabled on board analog card, that appears to be working. ( I rolled back the failed 1.0.11 install). Any ideas. Is the kernel source not included with R5D1? The NVIDIA driver compiled ok.

Ok, I have been doing some reading, and the on board sound, that has been disabled in the bios, is a via 8237. i am thinking of placing this in the alsa-base-balcklist file, therefore hopefully forcing the turtle beach card cmipci as the default card. I will try this when I get home tonight. And then I will post my findings in the morning.

Ok, last night after downloading and installing 1.0.12 from alsa-project, I still had the disabled card coming up in alsaconf. Here is what I did.
1st- Download the stable release of alsa


2nd - I manually loaded the cmipci (cmedia) driver

3rd - I commented out and added the cmipci driver to /etc/modules

4th - I rebooted, now the default card loaded on boot is the Turtle Beach (cmedia) card.

All is right in the world.
Hope this helps...
