Apart from .asoundrc file what are the other configuration files that
need to be taken care if we need to try mono and stereo headset.(HSP and
A2DP)
>> as far as I know, that is the only file required for a bt headset - I do not
>> have any a2dp headphones to test.
What is the significance of the audio.conf file in the /etc/bluetooth?
Whether this is required for the Bluetooth headset proper audio routing?
>> do you mean /etc/alsa/Bluetooth.conf - I don't have an audio.conf? The
>> Bluetooth.conf file is an example for .asoundrc
If you are using the audio.conf for the A2DP/HSP can you share what
additional configurations you have made.
>> [see above] - I am only using .asoundrc with a bt headset
Also can you please share your experience with the 4.41+ on your side
with the Bluetooth headset Mono or stereo.
>> it's working fine for me with 4.43 and a bt headset
Thanks & Regards,
Benjamin
