Playing audio through CD drives


Hi all,

I have a CD-RW drive and a DVD drive in my machine, both of which are connected to my Soundblaster Live! 1024 Platinum Card. Whenever I put an audio CD into either drive, and use any CD software, the software thinks that the CD is playing ie the song timers, etc all work, yet I have no sound. When I play MP3s from the HD, I have sound though.

Does anyone know what the problem is?

I've got a SB Live! as well. What have you got connected where?

Mine is
CDRW too CD Audio
DVD too Aux

I found the SPIDF unrealiable also it interferred with the other connections.

I have my DVD drive plugged into to the digital plug on the card, and my CD drive into the CD plug on the card. Under windows, my audio is fine, so I think that the connections are correct, and that there is something wrong in the drivers?? But I couldn't tell you anymore, because I don't know anymore!

What driver are you using?

emu10k1 seems to be the best for live! cards.

I am using the emu10k1 drivers, but have also tried other drivers all with no success. I'm thinking hat there is a setting for the drive incorectly set somewhere?

this is not a driver problem, at least not an audio driver problem. (unless the mixer is muted.. but you checked that right? (it can be on max volume and still be on mute, specially with alsa)) but when you play a cd the cd-drive plays it and outputs the audio to th soundcard already decoded/whatever, that is why some drives have headphone ports. the audio is just eather not comming out of the cd-rom drive, or the soundcard is not passing it through, but drivers do nto always matter, you can play audio while in cmos in many soundcards.

2 things to try:
1) when playing cd's use the headphone jack on the front of the drive if you have one, that will tell you if sound is comming from the drive.
2) try playing a cd without your sound drivers loaded, this will tell you if the driver is muting it/ not supporting it (disabling passthrough and volume
3) if the drive plays it and the soundcard is the problem, and no driver changes fix it: attach a stereo audio cable from the headphone jack into the aux-in on the back of the soundcard (the stereo port not the internal one)

Hi,

The headphones work from the front of the drive, which is a good thing...

How do I then go about disabling my drivers (I'm not very into drivers with linux just now)

Then, if it is the drivers that are the problem, how do I uninstall them?

Thanks,
Graeme

well, you can disable them n the kernel if you compiled it, you can remove emu10k1 module form the modules.conf, or there are a number of other things. redhat it might be hard without compiling because it autodetects. I forgot which you are running because of a combination of having 300 threads to respond to (not quite that many but a lot) as well as having spent the last 18 hours reformatiing and trying to fix a problem that was a combination of the nvidia patch for 2.6.0 and a bios revisionthat f_cked everything up and I am tired.. sorry.

If you have SCSI emulation on the CD/DVD readers. Run cdrecord -scanbus. Note down the SCSI bus for each drive. Next use either cdda2wav or cdparanioa. Both programs are console programs that digital rip using the IDE cable instead of using the audio and digital audio cable.

What do you have listed in your /etc/modules.conf file?
What does /sbin/lsmod show?

BTW, in LINUX, software that controls the hardware are called modules not drivers.
