I have two cdroms in my PC.
/dev/hdc -> /dev/cdrom is an LG cd burner,
/dev/hdd is a 52x ASUS cdrom
The problem I am having it that /dev/hdc produces sound from an audio cd, but /dev/hdd doesn't. The cd plays with fine, but has no sound. All sound effects and systems sounds work. My Sound Card is also working properly.
/dev/cdrom, hdc is using the driver: ide-scsi version 0.9
/dec/hdd is using: ide-cdrom version 4.59
How do I go about fixing it?

At a guess I'd say you have a 3 conductor (4pin) audio cable connected between your burner and your soundcard, and not between your cdrom and your soundcard. Hopefully, your soundcard accepts two cd audio cables. Many (most?) don't. I think there were Y cables of this type on the market but I wouldn't recommend that. Probably the best solution is to decide which drive you want to use as a cd player (cdrom;)) and plug into that.

Yes that is true.
When I stuck my burner in, I plugged the cable into the back of the burner into the sound card. However, Windows will play audio CD's fine from both the burner and CD-rom. I tried it out today and both were playing fine.
/dev/hdd will still not play audio, so I am unsure what the problem is. Even as root, there is still no sound coming from /dev/hdd.

The reason that windoze is fine is because it gets the data and decodes it in the cpu whereas linux calls on the cd drive for the "brains"
Hope that helps,

Thanks. Linux seems to run faster than XP, which is evident by your response. With Blackbox/Fluxbox it absolutely smokes. I guess the best thing is to just change the CD-audio cable back to the Slave (CD-rom) drive.

Exactly. Some versions of windoze extract the digital audio data via the ide interface and have the cpu and soundcard synthesize the audio from that. Typical windoze stupidity. Considering that all modern cdrom/cdrw's have a builtin music cd player that outputs via the audio cable and uses virtually no system resorces at all.
