OSS + CMI8788 Recording

Jimi · 2010-11-28 21:31:24

I use an HT Claro Plus sound card. I've basically been going back and forth between using ALSA and OSS. I don't know that much about OSS, but I still honestly prefer it.
I can't seem to get recording with my microphone (pink input jack, it isn't USB or anything) on OSS, but I can on ALSA.

I'm not even sure what the correct Input Device should be.

Setting up OSS might be a bit more of a pain than setting up ALSA, but when it's all said and done I think I'll prefer OSS.

Thanks for the response, and I apologize.

I tried switching back to ALSA, but I can't get recording to work once I start using dmix.
Really wish I could figure out how to get my recording working on OSS. Working with ALSA just makes my head hurt.
