Subject: [PATCH] fix(audio): fall back to track gain when album gain is
 missing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In album gain mode, tracks without albumGain tags received no
ReplayGain adjustment at all. Now falls back to trackGain before
defaulting to 0 dB — fixes inconsistent loudness across albums
where only some tracks have albumGain metadata.
