7 years ago @notaz what tremor version do I need exactly? I tried the version from gen plus gx and revision 19599 too (main and low memory branch), and I only got noise. What I did in the source:

A sample of the .cue file:
CATALOG 0000000000000
FILE "Sonic The Hedgehog CD (Japan) (Track 01).bin" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
FILE "Sonic The Hedgehog CD (Japan) (Track 02).ogg" OGG
TRACK 02 AUDIO

FILE "Sonic The Hedgehog CD (Japan) (Track 03).ogg" OGG
TRACK 03 AUDIO
INDEX 00 00:00:00
INDEX 01 00:01:74
As the bug's title says. I'd like to see ogg as an option for the audio, as I'd like to take my rips and just store the ISO+ogg files on my backups instead of having to do mp3 as the bitrate required for that to be perfect is ~2x that for ogg.
I don't know the performance characteristics for the streaming of the audio on the devices that you're doing, so I'm not going to suggest FLAC as decoding flac might take up too much cputime.
