Title: aplay and arecord issue ?
Post by: iw2iol on June 18, 2013, 05:10:39 PM

Hi all, I'm trying to record some sounds (and play them) via arecord without success using my Olinuxino Maxi board. Is there anybody that can advise me? I tried different combination via amixer / alsamixer
but, nothing....

i.e. arecord -d 5 -t wav -f cd a.wav
aplay -d 5 -t wav -f cd a.wav

Thanks, Dario.

Give us your Linux version uname -a and aplay output too.

Hello, here some more details

uname -a
Linux Olinuxino 2.6.35-8-ARCH+ #1 PREEMPT Fri Sep 21 17:02:25 UTC 2012 armv5tejl GNU/Linux

The 'problem' can be easily seen running arecord as follow:

arecord -f cd -V stereo /dev/null

The vumeters show that the signal is coming only from one channel even if I'm injecting a stereo signal into the bord.
The mixer has been set of course as follow:

Left ADC -> Line In 1
Right ADC -> Line in 2
HP Mux -> DAC OUT

Am'i missing something ?

Thanks, Dario.
