[S.u.S.E. Linux] Sound: CD playing doesn't work
Hell folks, SuSE 5.1 here. I am able to cat foo.au > /dev/audio and hear sound through the speakers. I am able to use rvplayer to listen to Real Audio on the net. I am not able to listen to an audio CD through the speakers (headphones work). /dev/sndstat looks ok (will post if needed). the files in /dev (/dev/audio, /dev/dsp, /dev/midi, /dev/mixer, /dev/music, /dev/patmgr, /dev/sequencer) all look to have the correct major and minor numbers. /proc/devices shows the sound driver compiled in. The card is an ESS1688. Anyone able to help? -- Mike Fieschko, who lives in West Orange, New Jersey, USA fieschko@viconet.com - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
HiHo...
I am able to cat foo.au > /dev/audio and hear sound through the speakers.
I am able to use rvplayer to listen to Real Audio on the net.
I am not able to listen to an audio CD through the speakers (headphones work).
you need a cable from the sound card to your cd- is that available ??? o far... - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
Check the CD-Rom audio cable. It should be plugged into your sound card and into the back of the cd-rom. It sounds like yours is not connected or has a bad connection. On Tue, 7 Jul 1998, Mike Fieschko wrote:

The cable is connected. I will check again to see if the connection is tight. But if the connection was bad, wouldn't a cat to /dev/audio produce no sound? Likewise no sound, using Real Audio's rvplayer? I do suspect a hardware problem, since the symptoms (all sound is OK except playing a CD) are the same in Win 3.11. The CD-ROM is an NEC scsi model 222. Is there a particular audio cable to use (a different one than for IDE CD-ROMs) for a scsi CD-ROM? -- "My attitude toward progress has passed from antagonism to boredom.

No. There should be three cables to the back of the cd-rom (if it is internal) A power cable, a (scsi or ide) cable and an audio cable. The audio cable only carries an analog signal from the cd-rom directly to the amplifier portion of the sound card. The sound card does not need to be supported for the cd-rom to play music.

The CD-ROM is an NEC scsi model 222.
If this is an external NEC cd-rom, there should be RCA outputs on the back. Those would have to go to speakers or an amplifier.

An audio cable is simply three wires (Left signal), (Right signal), and ground. Most cdroms and sound cards can use an MPC II audio cable.

Yeah, there is a flat scsi cable and a power cable also. (I'm a newbie, but not quite _that_ much a newbie :-)!)
The audio cable only carries an analog signal from the cd-rom directly to the amplifier portion of the sound card. The sound card does not need to be supported for the cd-rom to play music.
Does this ("the sound card does not need to be supported ...") mean that the audio signal from an _audio_ CD, travels over the scsi cable? (I don't think that is what you mean)?

The drive is internal. There is an additional place for a cable to be connected. The back of the drive looks something like this: . . .... .......................... .... | | | | no cable scsi cable to drive power cable to controller cable sound card Ought there be a cable connected to the extreme left location? -- "The truth is, of course, that the curtness of the Ten Commandments is an evidence, not of the gloom and narrowness of a religion, but, on the contrary, of its liberality and humanity.

Just checking.. :P i guess i am too used to the people i work with.

heavens no.. the audio signal travels over the audio cable to the sound card. Most sound cards do not even need to be initialized to make the amplifier portion of the sound card work. the problem sounds like one of the following. 1 broken cd audio cable. some of these cables tend to be very fragile.. 2 broken connection pins on the back of the cd rom.. (they are connected to the same circuitry the headphone jack on the front of the cd rom is connected to) 3 bad connection pins on the sound card.

Ought there be a cable connected to the extreme left location?
maybe not.. it is probably a digital audio out port and has two pins.. - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
i had the same problem with an awe64 in win95, what i did is replace the cable and it worked fine... Mike Fieschko wrote:
