Yes. Always.

Well the old a2dpd had a note in the configuration file saying the
following. Is there a way to adjust it in the current a2dp implementation?

# Allows to specify the sbc bitpool, this can help reducing bandwith
# 8 Allows to run on a 115200 bauds with corresponding quality ;)
# 64 needs USB or 921600 bauds
# Recommended value from Bluetooth spec. is 53
sbcbitpool=53
