It could also be that your CD drive is not connected to your sound card with an audio cable. Since Windows uses the IDE interface to play CDs rather than the audio cable most new PCs don't have one (I presume the manufacturer must save a couple of pennies per box by this or something ;-)). To get around this with XMMS go into preferences then the configuration for the input plugin "CD Audio Player [libcdaudio.so]" and set "Play mode" to "Digital audio extraction" rather than analog.

Kernel 2.6 also does not need IDE SCSI emulation for writing CDs anymore, so you normally use the IDE device files. However they belong to the disk group, and you have to change the device file for your cdrom to group cdrom. And don't forget that you need a cable from your CD-ROM drive to the sound card, or you need to use the cdread plugin. best regards Andreas Janssen -- Andreas Janssen <[EMAIL PROTECTED]> PGP-Key-ID: 0xDC801674 ICQ #17079270 Registered Linux User #267976 http://www.andreas-janssen.de/debian-tipps.html -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

sound/CD player question
I am running Sarge with the 2.6 kernel (that one that came with the installer) I got XMMS playing radio. However I cannot play CDs as normal user, and as root it shows the countdown of the seconds, but I get not sound output.

Re: CD player question
Hi Micheal, Generally CD roms play audio cd's in the following way. The CD-ROM reads the disk at 1x speed and converts the data to a audio signal via the internal DAC. The audio output of your CD-ROM should be connected to your sound card via a wire seperate from the power cable and the IDE or SCSI cable. The soundcard used this audio signal as just another analog audio source and feeds it into the audio mixer just before the speaker outputs. The soundcard does NOT do any manipulation of the audio signal in the digital domain. (Basic soundcard here) Therefore your soundcard and CDROM may be doing as they should but are missing the audio connection between them. You may have to puchase such a wire and install it. You can verify you CDROM is working correctly by pluging in headphones to the jack on the front of the unit. Using the software of choice command your CD-ROM to play an audio the CD. If you hear music you CD-ROM is OK. Look at the connection or the soundcard.

CD player question
Could anyone please explain to me how the CD players put out the music? It seems I'm having a problem with the sound card on one of my systems. I have one with a isapnp Sounblaster that works fine. For instance I can use play to play wav files, splay for MP3s, saytime tells me how late it is and xfreecd as well as gtcd play the CD. The only thing that doens't seem to work is emusic. But I didn't try more than just hitting PLAY on emusic so there is a lot of room for missing configuration on my part. My other system using an es1370 chip set PCI card that is (wherever possible) identically configured. I have no problem playing WAVs and MP3 with play resp. splay. But that's about it. None of the CD players gives me any output. But I also get no error message at all. And saytime produces some static in the speaker. Now saytime uses /dev/audio while play/splay use /dev/dsp, so this may explain thsi difference. but why doesn't /dev/audio work? And why do all the CD players not say a word? As a last note on teh PCI system all works well when using M$. Good sound from the CD. Michael P.S.: Please CC me on replies. -- Michael Meskes | Go SF 49ers!
