Hello everyone,
I'm new to both this list and to fiddling around with alsa, but I have a problem I hope you'll be able to help me with.
Basically, I have three conference room-style microphones (or better said, microphones arrays) with 7 (namely 8, but one doesn't work) channels each. Here is what i have https://www.minidsp.com/products/usb-audio-interface/uma-8-microphone-array
I need to simultaneusly record from all three of them at once for a project I'm working on.
I thought I'd be able to do this by tricking audacity into thinking there was a 24 channel interface an so I wrote a .asoundrc that I'm pasting below. This version includes only two microphones arrays but it already doesn't work.
What happens with this .asoundrc is that I can see both "aa" and "ab" in audacity and I can successfully record from them. However, there is no "aaa" nor "oo".
If anybody could help me solve this problem I would really appreciate it. I don't necessarely need to do this using .asoundrc, so if you have a better solution to my problem, please let me know. Also, please do not hesitate to ask for any further piece of information I might have missed. One last thing, I don't know if this mailing list is the proper place for my kind of problem; if it's not, I'd appreciate if you could redirect me to a more suited place to seek help.
Thanks a lot for your time and help,
Cheers,
alberto
