Hello Oguzhan,
It seems that no hal json configuration file has been
detected by
hal-manager at loading.
By default, all hal json configuration files are deployed
in
'/usr/libexec/agl/4a-hal/etc.available' and needs to be
moved in
'/usr/libexec/agl/4a-hal/etc' to be detected by
hal-manager.
Could you check that your configuration file is deployed
in
'/usr/libexec/agl/4a-hal/etc' ?
If not, can you move it into '/usr/libexec/agl/4a-hal/etc'
and restart
4a audio service by using systemctl command :
- To get the exact name of the 4a audio service :
systemctl | grep
service-audio-4a
- To restart the service : systemctl restart XXX (with
XXX the name of
4a service)
If your configuration file is in the right directory and
you still have
an error, I will need the results of these commands to
help you :
- journalctl | grep afbd-agl-service-audio
- ls -lah /dev/snd/by-path
- aplay -l
- amixer -D hw:X controls (with X the id of your card
result by aplay -l)
Regards,
Jonathan.
