it always produces some glitch when resuming (during the playback it
seems alright):

Can you send btmon/wireshark dump? I can inspect aptx HD packets if
decoder can correctly decode them.
Those messages from module-loopback are normal and expected.
They just show that module-loopback is adjusting the initial latency
to what is requested. If the source or sink is not ready when the
loopback starts processing data, it means that either the latency
will grow (if the sink is not yet accepting data) or shrink (if the
source is not yet providing data). Module-loopback tries to
compensate by dropping samples or inserting silence.
