Using VL SOHO 5.9. I have a motherboard with an onboard Via AC97 sound chip, which I have TURNED OFF in BIOS and also have a better Audigy 2 sound card (which is the one I prefer to use). Despite having turned off the onboard audio chip in BIOS, VectorLinux is still detecting it.

So what happens, is that on a seemingly random basis the system sometimes decides to use the Via chip and at other times the Audigy chip! Weird! I can tell which one by opening alsamixer. This is frustrating to say the least. Despite using vasm and telling it to use the AUdugy chip it seems to make no difference either.

Does anyone know of a way to force alsa and the system to use the Audigy chip?

Here is relevent lspci output:
Code:
00:0d.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04)
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)

Thank you. I feel like a real prat now as a simple search would have saved me a lot of typing. Being a  forum moderator makes it even worse! Doh.  Embarrassed

Hahaha I thought about that while writing, "I hope Larry will not take this link pointer as an offense", but then I remembered the search function doesnt work right after the forum move Wink

Same with me with a webcam mic.
It works fine after doing the headacher fix, but it seems very random.

If I just leave vector be, it will sometimes get me one or the other as the default.
