Hi bultel,
There is a file descriptor under the device node:
raspberrypi3:/dev/snd/by-id# ls -al
total 0
drwxr-xr-x. 2 root root 60 Aug 8 08:49 .
drwxr-xr-x. 4 root root 380 Aug 8 08:49 ..
lrwxrwxrwx. 1 root root 12 Aug 8 08:49
usb-C-Media_Electronics_Inc._USB_Audio_Device-00 -> ../controlC2
And i copy the "usb-C-Media_Electronics_Inc._USB_Audio_Device-00" and
write to the configuration file but it still doesn't work. Does it have
something to do with the '.'?
The '.' should not be an issue at all.
Could you please show again your /var/log/message ?
Should I configure others keys in the
.json file?
Now, i add a .asoundrc file at ~/ directory, and set external sound card
as default sound card, it works temporarily. But i don't know why it
doesn't work when i modify the configuration file.
4a does not need a .asoundrc to work.
And another question, i found that when 4a service start, a binding
called "4a hal manager" start also, but i didn' find the code on gerrit,
and i also follow your github id, and IoT.bzh github id, still not
found, where could get the code? Thanks very much!
It is at https://github.com/iotbzh/4a-hal-generic
Cheers,
Sitech

Hi Sitech,
Please have a look at the "playbacks" section in the .json file.
The playback device is identified by the /dev/snd/by-id entry
In the version in git, you have
/dev/snd/by-id/usb-0d8c_USB_Sound_Device-00
which is one of the devices we support and that is used in our tests.
With aplay, it is listed as such:
card 2: Device [USB Sound Device], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
I am pretty sure that yours does not match this one, since on my side
the short name is "USB Sound Device" and on yours, it is "USB Audio Device"
Please check what you have in /dev/snd/by-id and try to put it in the .json
Cheers,
Thierry
