Hi @mikerobertsn,
0 is not likely to be a valid device ID.
Try using:
aplay -L
You will see multiple entries. For me this is the correct one for the USB device:
hw:CARD=Device,DEV=0
USB PnP Sound Device, USB Audio
Direct hardware device without any conversions
...from this, the part that you need as the ALSA device ID is:
hw:CARD=Device,DEV=0
Then you can try arecord
again:
arecord -f S16_LE -r48000 -c1 -D hw:CARD=Device,DEV=0 | csdr mono2stereo_i16 > ~/test_audio.raw
Does this help?
Hi, my usb sound card shows up as device 0, but when I run sudo arecord -f S16_LE -r48000 -c1 -D 0 | csdr mono2stereo_i16 > ~/test_audio.raw
to test the audio card I get an error of
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM 0 arecord: main:722: audio open error: No such file or directory
Any ideas???
