Hi All,

I have a question about sound control.

My motherboard has a built in sound chip with 7.1 surround and a six jack I/O block. It uses the snd-hda-intel module and shows up as Realtek ALC883. It works just fine as is. But since I don't have a surround system on my PC, I have a question.

Can I change the way the I/O works?

On the widows side of my box, the software lets me configure the 6 jacks as I see fit. Basically turning them into a patch bay. The setup I use there is a follows.

Jack# Desc.

1 Mono In (Mic)
2 Stereo In (Line from TV card)
3 Stereo In (Stream capture from 5)
4 Stereo Out (PC Speakers)
5 Stereo Out (Stream to 3)
6 Stereo Out (Wireless to Stereo in another room)

As you can see, this is quite useful. Is there a way to do this with Linux?? I have been using Linux for a long time, but can't seem to figure this one out. I have played around a little with JACK Audio, but can't seem to get it to work without screwing something else up. Is there a way to set this in the module? Or is there an easier way to do it I just don't know about??

Thanks for any help you can give.

Hi Snocrash, I'm not sure if you can change the I/O but, you might be able to map them using an .asoundrc or something similar. There are several descriptions here.
Good luck. ;-)
