BT audio not always routed correctly

[piggz]

This is probably some weird corner case, but i will raise it now that you support BT_SCO param.

Sometimes audio is not correctly routed to my car kit. Example, today, i was in the car, and I have 2 BT devices, 1 for audio only and and the car kit. Phone is paired with both. I was playing audio to the audio-only device, which always worked. I then disconnected both devices, and connected to just the car kit and made a call. No audio was connected, and I had to use speaker.

Please indicate which logs would be most useful.

Please indicate which logs would be most useful.

logcat, pulseaudio and ohmd.. make sure to disable rate limiter before taking logs from journal.

usual things to enable logging, for pulseaudio
. /etc/sysconfig/pulseaudio ; echo "CONFIG=\"$CONFIG -vvvv\"" > /etc/sysconfig/pulseaudio

for ohm install ohm-tracing package

disable ratelimiter

sed -i 's/.*RateLimitBurst.*/RateLimitBurst=0/' /etc/systemd/journald.conf
sed -i 's/.*RateLimitInterval=.*/RateLimitInterval=0/g' /etc/systemd/journald.conf
sed -i 's/^RuntimeMaxUse/#RuntimeMaxUse/g' /etc/systemd/journald.conf

After these reboot and take logs of all use cases, working and failing
