Distorted sound after commit 45af1a7

[Galicarnax]

Problem

After building the latest version, the sound in BT earbuds is distorted. Reverting to the version I used previously restores the sound quality. I have tried building intermediate commits, and found the one after which the issue arises: 45af1a7.

Looking into journalctl -u bluealsa.service, I see nothing suspicious. The systemd service is the default one provided in your project: ExecStart=/usr/bin/bluealsad -S -p a2dp-source -p a2dp-sink. The output of bluealsactl info <pcm> also shows no difference between the versions:

Device: /org/bluez/hci0/dev_B0_4A_6A_0F_87_94
Sequence: 0
Transport: A2DP-source
Mode: sink
Running: true

Selected codec: AAC

I can provide any further information on your request.
