Summary: emagic a62m: maybe bug: arecord doesn't record
anything, jack+jackrec work
Description:
When I want to record something from my emi a62m audiointerface, arecord
doesn't work:
"arecord -D emi -f cd > test.wav"
when issuing "aplay -vvv test.wav", the histogram shows up a permanent
peak of 36% during the whole file, no sound hearable.
Starting "jackd -d alsa -D emi" and issuing "jackrec -f test.wav -d 5
alsa_pcm:capture_1 alsa_pcm:capture_2" does record a valid file.
.asoundrc:
pcm.emi
{
type hw
card 1
}
ctl.emi
{
type hw
card 1
}
Card 0 is a solo1.

I noticed one more thing:
If I call:
> arecord -D emi -f cd | tee test.wav | aplay -D emi
the file "test.wav" contains valid recording data!

Could you already figure out, what's going wrong?
It seems to be a reasonable easy solution to open the device reading _and_
writing (capture + playback), while recording. Is it possible to simulate
that via a .asoundrc-file?
