Hi,
I have bluealsa service running on yocto linux and able to connect bluetooth earphone. I can able to play and record using below mantioned commands,
aplay -D bluealsa:SRV=org.bluealsa,DEV=xx:xx:xx:xx:xx:xx,PROFILE=a2dp /usr/share/sounds/alsa/Front_Center.wav
arecord -D bluealsa:xx:xx:xx:xx:xx:xx,sco -d 5 test.wav
While recording/playing audio i'm not getting any signals on PCM lines, but on uart. How can I test PCM (want to check singals on PCM lines)?
Note:
this is what /usr/lib/systemd/system/bluealsa.service have (logs are trimmed)
# cat /usr/lib/systemd/system/bluealsa.service
.
.
.
ExecStart=/usr/bin/bluealsa -p a2dp-source -p a2dp-sink -p hfp-hf -p hfp-ag -p hsp-hs
.
.
.
and this is output of bluealsa-aplay -l
# bluealsa-aplay -l
