Bug#990106:

[Davide Beatrici <me@davidebeatrici.dev>]

I've been using the AVR-X1000 for a few days now and the problem is no more.

I also realized the AVR-X500 has another issue: the volume of the surround (rear) and subwoofer channels is way too low.

With the new amplifier all channels have proper volume, without individual tuning.

Sorry for the wrong bug report, free free to close it.

Hopefully it will be useful for someone encountering a similar issue in the future.
