OK, all you Linux hardware experts, I have an interesting dilemma for you to discuss. I recently set up a system for my brother that is using an older MSI RS480M mobo that was originally in an eMachine. It has standard baloney onboard audio. However, I had a nice Dynex DXSC51 sound card just lying around out in the shop, so when I set the system up for him, I included the high perf sound card. It works great in MS Windows. However, Linux Mint does not see the sound card (PCI). It only sees the AC-97 onboard audio. In the past, when I've run across a Linux distro that behaves like this, I've just disabled the onboard audio from within the BIOS and VOILA! Linux detects and uses the PCI sound device. That's not a happening fix in this situation, though. The BIOS has no provision for disabling onboard audio. Anyone have any other suggestions? Keep in mind, this will be difficult for me to troubleshoot because the system is 800 miles away from me in Fairfax, VA now. Are there any other possible ways that I can get Linux to use this card? Or is my brother doomed to using the onboard audio?
