I've noticed that since updating to 1.4, replaygain track-scanning files with a 192khz sample rate produces only a track peak instead of both a track peak and track gain.
I noticed this when I replaygain scanned a new flac album. I found older flac files in my collection with the same sample rate that successfully replaygain scanned some time ago. I deleted the replaygain info on these files and tried to rescan them, which produced the same problem. Because of this, I'm pretty sure the foobar update is behind it. Not much else could realistically be causing such an issue.
I can experience this if "Downsample high-definition content" option is checked and resampler is either dBpoweramp/SSRC or SoX. PPHS is fine.
edit: nvm
Confirmed and fixed for the next update, thanks for reporting.
Awesome, thanks
