Hi.
I am using a M-Aduio Delta 1010, with a setup that I have 8 single
input/output channels. That works great with ALSA, and I can record and
playback simultaneous on all channels.
What I want to do, and up till now not found a solution for, is to record
one output channel and one input channel simultaneous to a stereo file.
The use case for this is, that I want to measure the delay of a external
communication system in an automatic way. So I playback (aplay) a wav sample
out off channel 1, send it via my external communication system and record it
back via channel 2 (arecord).
This will end up in 2 none correlated files. Want I want to have is a device
where I can record a stereo file (arecord -D out_in_mix ...) that will have
channel 1 output (left) and channel 2 input (right) of my Delta 1010 in it
OUT1 ---->---------
| |
| V
REC -<- ----------
Stereo-<- |Com Ext.|
| ----------
| |
| |
IN2 ------<---------
I tried with the dmix and copy plugin, but so far no luck.
Any suggestions are welcome.
Regards
Peter
