Over the last couple of days I've had an issue with my Sony STR-DH520 with the volume
I have always had the volume set at 15. Then adjusted the Mysky volume which usually runs at about a quarter to achieve a normal listening level.
In the last couple of days something has happened, and I've had to double that to 30 on the amp to achieve the same volume. This is the same for any source, Mysky, apple tv, or streaming audio. I've tried all the different sound fields, checked the speaker loudness, checked my connections, and done a couple of auto calibrations with no improvement.
Does anyone have any idea what might be going on? Everything else is running as normal, I just can't understand why I would have to double the volume. TIA
