yea so i play a cd through rh9, it says it's playing, but i hear nothing...what's the deal?

also...how do i look at what's on a data cd/disk when i put them in the drive to try and look at them in rh9?

Check the audio mixer to be sure the CD volume control is not set to min volume.
Do you have an audio cable between the CDROM drive and the sound card?

You need to mount the CD before you can view its contents. Either click on the desktop icon or right click and select mount or open a console window and use the command

mount /mnt/cdrom.
warheros
well...i thought maybe it didnt detect my sound card, which i do have because i dual boot between rh9 and winxp-pro and have played cd's there, and it knows the sound card is there, even played a test sound for me. and i went somewhere about disk management and it shows my cd drives and floppy drive...checked volume, it's up.

Okay, this might sound a bit odd, but i've had a bit of trouble with the whole sound stuff.

Some windows CD players can be set to process the info from the CD, takes up proc speed but mean that the CD drive sound chip isn't plugged into the sound board on your PC. I'm not saying this is the case, but one way of checkin it out is (only if your drive has this 2 out of my 3 cd drives on my tower has this) is a play button next to the eject, put in an audio CD (no autorun) and hit play. The lite'l flash, the disc will spin, if you hear music you know that there's a sound cable between your CD and moby/s'c.

You could try this by playing a CD in linux, same process as above (if it spins up the CD) and throw you spk cable into the jack socket on the drive, if it works then there prolly isn't a cable between cd and moby.

i have no play button on my cdroms. also, rh9 opens the cdplayer program, and the disk spins throughout playback, but i hear no sound. the time and everything is going i just hear nothing. it is odd...
Jay-Jay
When it's playing under linux, take the audio cable for your speakers out the back of your pc and put it in the whole on the front of the CD drive. This will let you identify the problem more accurately. If it plays then there's a problem with 2 things.

1. There's no sound cable from the back of your CD drive to your motherboard

2. There's a software problem.

Try the above suggestion for checking in windows, that will rule out 1.

all right...and do you have an AIM s/n, it may be easier to go back and forth that way rather than waiting for a post.

Hiya,

No, it's a long story but I'm sat behind a lovely server capible of doing so much more but I'm extremly limited, they will only let me MSN. If you can MSN me I'll be up for a bit but it's 00:24 my time.

ok, plugging the cable from my speakers on the sound card to the jack on the front of the cdrom works. i can hear music now. what do i do to fix it so i dont have to have that cable on the front but in the back where i want it/where it was?
Jay-Jay
Okay, theres a couple of options now we know where the problem is.

The CD drive is sending the correct info but it's getting lost somewhere.

Unless you've done some mod's to you machine since purchasing you 'should' have a cable that runs from the back on the CD drive (internal) to the motherboard sound proc(essor). Im guessing that if you don't know 100% if theres a cable that you havn't done mod's and that that's not the problem.

I'm a little bit at a loss as what to do now, because I have no idea about software available for music on linux (i'm pretty new, and i've got my own problems on my laptop) But I'm like 98% sure that it's a software problem under linux.

If you're 100% sure that the volumes are turned up on your sound mixer (and the mute buttons (if there are any mute buttons) arn't checked) and that theres no other volumes elsewhere that could cause there to be no output to the speakers, then I don't know what you can do.

If you had a spare stereo jack to jack cable, you could plug it in the jack on the CD drive and put it in the line in / mic on your soundcard. I've had to do that on my drive as I don't have enought internal inputs on my sound card. This might work if it's a software problem, but only as a botch job and it isn't solving the underlying problem. (It's like sweeping rubbish under the sofa.)

I'd sit it out here, someone else mite know what the problem is.

This is one of the reasons that i'm making a PAQ's page for this site when I come back from summer holidays!!!

I am having the same problem. While plugging headphones into the jack built into the cd rom will allow music to be heard. Unplugging it and trying to get sound to come out my speakers is yet to work. My sound card runs through my stereo which in turn sends the sound into the speakers. While this setup works for me in win Xp and other windows os's (98se, 95) I have yet to have it work in linux. A year ago when I last messed with linux I had thought that my sound card was just not compatible, and I do believe I even found it on a list of incompatibility, with ANY linux distrobution. Since it is running directly out the jack built into the cd rom would it therefore bypass the operation of the sound card? Thus, here within is actually the problem? A non compatible sound card? Just a thought and my 2 cents to this thread. I'll continue to follow it and if I find any proof or if I come up with a fix I'll definately let everyone here know about it.
warheros
well...

i got a mp3 decoder for xmms that actually installs correctly and works, and BEHOLD! i can now listen to mp3's in linux rd9 in xmms, with all the cords plugged into the correct jacks on the back in the sound card. havent tried the cd thing yet...but then again...i dont believe i even played a cd in the cdrom in winxp pro...so yea.
LinuxHatesMe
mp3 decoder.. xmms... sound eh? Well I'm just trying to get ANY type of sound to work. I have yet to bring up my network computers so I can test this idea as of this moment. But I'll start work on that because it may push me towards my goal of SOUND. WOOHOO, these things you take for granite. I have ALL sounds turned off on WinXP and here I am wishing and praying that I can get some sound out my Linux box, lol. Like they say, be careful what you wish for I suppose, may not turn out how you want it to. wink.gif
Jay-Jay
Well for you both then, I suggest that you just go out and buy a short jack to jack. Plug one into the 'headphone' socket on the CD drive and the other in your line in on your soundcard.

Thatway you should get the CD drive to play audio cds, short term fix that'll work.

Jay-Jay
Jay-Jay
Hay warheros,

What player did you get? And where did you get it from?

Thanks for lettin' me know in advance!

Jay-Jay
michaelk
Redhat didn't include the MP3 decoder by for xmms. I guess they are afraid of copyright infringement.

XP uses digital data extraction from the CD to play audio but linux and win98 still requires the audio cable. I thought that some digital CD player is out on linux some where but don't remember where I read it at.
Jay-Jay
Good call. I didn't know that XP uses a digital CD player as default. So i guess that there is no need to run an extra cable when you don't need it. Well, you learn something new everyday!

I'm constantly wondering why there isn't so much support for linux related to sound!

Jay-Jay
warheros
player? im just using the xmms player (looks like winamp)? it's in the rh9 installation cd's.
Jay-Jay
Warhereos, Try googling for a digital CD player for windows. You might have more luck that way.

What windows OS do you use?

Jay-Jay
warheros
well, it crashed, but it's windows xp pro. that's why i switched to linux rh9, i was friggin sick of windows blue screening me.

then again, i didnt really pay for xp pro...smile.gif
LinuxHatesMe
If you mean that, you didn't really pay for win xp, that you got a non legit copy. Your answer to your blue screening is probably that. If you downloaded it, most likely it has a virus or backdoor and some important files are missing also from it. If you just copied it from an actual legit/non legit copy of win xp then perhaps the cd didn't burn right, even if it did said the burn was ok. Happens sometimes. Or if you mean win xp came with the system when you bought it, that could be another reason because I find that os's that come pre installed with system's aren't always that dependable and doing a format and full install of an actual windows install cd rather than a dell or gateway recovery cd will fix the problem.
warheros
i got it from someone on a burned cd, it worked fine for like...6 months or so?...then it suddenly started blue screening me. my guess is that it deteced that my serial no. was not legit.
LinuxHatesMe
Naw, Windows software isn't that smart, don't listen to what they say and all that. 6 months seams about the max lifetime of ANY of my windows installs. And not just because I mess around with them. One time I had 2 diff harddrives with 2 XP installs, again just for testing. The one install I didn't mess with except for adding the updates and security patches lasted around ht e6 month range and just started acting screwy. So I reinstalled it and no probs after that for a bit. Finally finished my testing and just kept the first install in which my games and everything was on and still had problems with that. This is the whole reason I started my linux journey. Windows is NOT stable every, I don't care what other people say. Except for the windows server or NT versions you won't see a stable install last over a year.
warheros
well...i dont know though...that could be...but i could never download and install windows xp pro service pack 1, it always said my serial was wrong. maybe that's why it finally crashed...all i use my windows partition for anymore is to store music on. and as soon as i get my modem working with rh9, i will bid windows farewell.
