I though the audio got transferred over the IDE cables these days.
I haven't plugged an audio cable into a dvd-rom/writer for years.
Just tried it,
burnt Audio CD
Stick it in Liteon 811s, PC plays audio cd in media player
Stick it in BenQ 1640, PC sees blank disk
Stick it in NEC3500a, PC plays audio cd in media player
printed Audio CD
Stick it in BenQ 1640, PC plays audio cd in media player
No audio cables connected to any drive, BenQ can't see the data on the burnt audio CD ffs.
