not able to hear sound while playing audio cd's


Hi,

I am using RH9, when i insert a audio cd the CD player starts automatically and it shows the track being played but i am not able to hear any sound, i tried increasing the volume bar but i could not hear anything.

I am able to hear system sounds and events, and even play movies with mplayer with sound, only with this CD player i am not getting any sound.

I have even kept the system master volume to maximum, what else could be the problem, when i am able to hear sounds using xmms,mplayer etc.

Please help me i am not able to play any audio cds.

Thanks,
Christopher.

Has this cd-player ever played cds?
It may need a jumper wire from the back of the cd player to the sound card.

Also look at alsamixer (if you're using alsa for sound). There may be a separate volume control for CD. Or it may need to be unmuted.

this sounds like a jumper wire problem. to be totally sure, you could try playing the cd with xine. if this works, then you don't have a jumper wire installed between cd-player and motherboard/soundcard.

Please tell me how to configure xmms to play audio cd, I have installed the cd-read plugin, in the editor it shows that the track is being played but i hear no sound.

I dont know how to install xine, please tell me why i am not able to hear any sound even while using xmms since it does software decoding.

okay, the way i see it, xmms doesn't do software decoding of cds (at least it doesn't on my system). and i can't see a way to tell it to use the xine-engine (maybe an option during compilation, but i'd be surprised if it isn't easier than that). so if you really want to use xmms to play cds, you've gotta open your computer and connect a cable between the cd-drive and the sound-card/motherboard or go to www.xmms.org and ask them.

you probably already have the xine engine installed (check that by looking in /usr/lib for anything called either xinelib or libxine) and can access it over caffeine (or whatever the standard video player front-end is called on your system). the standard video player front-ends tend to offer, to the best of my knowledge, a button you can press to play a cd (usually using the xine engine). mplayer, if i remember correctly, uses a different engine as default. try playing a cd using it.

if this works, the missing cable would seem to me to be the next thing to check. just open up the side of the computer (assuming it's a desktop) and count the cables attached to the cd-drive. if there are less than three of them, then the missing one is (probably) the sound-cable.

Lack of sound on cd/mp3 player

Hi

I appear to have a similar problem on Suse 10.0. Ever since installing it I have been unable to play either the cd player or amarok/xmms. I shall qualify that and say that
on some rare occasions amorak has worked for a short period. When it does it plays one tune only then crashes. I have KDE sounds (beeps etc)but that is all.

I can play dvd's using xine with full sound. Originally the OS could not find my sound card and I had to install it using YAST. However while messing about with something else I appear to have fixed this as it now loads the card modules on boot up.

I ran amorak from the command line and got the following error message when I tried to play an mp3 file.

grabro@linux:~> QObject::connect: Cannot connect QSignal::signal(const QVariant&) to (null):null)
QObject::connect: Cannot connect QSignal::signal(const QVariant&) to (null):null)
QObject::connect: Cannot connect QSignal::signal(const QVariant&) to (null):null)

Perhaps somebody may know what this means.

if i remember correctly, on suse 10.0 amarok doesn't support mp3, because mp3 is not a patented codec. but i imagine you already knew that. apart from that i dunno what to suggest. a friend of mine has had similar problems with amarok crashing (i installed the mp3 libraries for her), but everything crashes on her computer, so something's not right with the hardware in her case...

Remove xmms and its CD audio plugin. Next download the source code for xmms. Compile xmms with DAE (digital audio extract) support. After is done compiling and installing, configure the CD audio plugin to do DAE. When you tell xmms to open up the CD disc, it should play the audio. However, the audio is played through a PCM stream, so you can only play just the CD audio if the sound card or driver supports one PCM stream at a time.

MP3 is patent by MPEG, so commerical Linux distributions can not contain it. They could include LAME which is a free MP3 codec that is written differently than the MP3 codec, but it reads MP3 audio just fine.

The cable is not a jumper. It is a CD audio cable. The quality is crap, costs money, and it takes time or is painfull to connect it.

No sound on cd

Hold_Breal

On some ocasions it does play at least one of my mp3 files then crashes so it does play mp3 files. The cd player also works fine using both Mepis and Windows 98SE. Amarok also works great on Mepis.

@gabro:
can you try playing an ogg file using ogg123 from the command line? if that works, can you try playing an mp3 using xine from the command line?

@christopher_1:
first of all, you have to download the sourcecode
then there should be instructions with it, usually in a file called README or INSTALL. i don't have the time to look at this myself, but these things are usually pretty well explained.
