and so I found out something
1) changing the kernel to the one suggested did not help, the situation remains
unchanged
2) when the A2DP+AAC profile is set, when trying to make an audio call, the
profile tries to switch to HSP/HFP and cannot do this, but if the A2DP+LDAC
profile is initially set, the profile switches to HSP/HFP without problems

As far as I can understand, the issue here is definitely not in the kernel, but
I don’t understand what target to choose for this bug report if not the kernel,
I would be grateful for a hint.
