Per https://datatracker.ietf.org/doc/html/rfc7845#section-5.2.1, opus files are not supposed to use REPLAYGAIN_ style tags, and are instead expected to use corresponding R128_*_GAIN tags for volume normalization. The tags indicate a gain using the EBU R128 standard, with a target loudness of -23dB. In comparison, ReplayGain2 targets -18dB. Because of this, several players I use (e.g. Foobar2000, PowerAmp), will use the R128_*_GAIN values for replaygain, and automatically add +5dB to keep the normalization consistent with replaygain.
In the interest of following the RFCs, my music collection has a number of opus files, which I have normalized with R128 tags. Unfortunately, navidrome doesn't currently read these tags, so my opus files don't end up with any gains applied, causing volume mismatch. There are ways around this with opus output_gain, but I think it would be nice if navidrome could read the R128 values like REPLAYGAIN tags, and apply the +5dB to them.
