I will check later that this is the case. The volume could be muted by default for the CDROM line. Did you check with mixer(8)?

I thought there was a technical way of reading the CD track as data and write the samples to the audio driver? It was called "paranoid" access or the like and was meant for people who did not have this audio cable on the CD drive. It worked in much the same way as the CD ripper but played the data instead of saving them to disk.

Thanks, Rahul Trying to simplify the difference: the sound from a mpg/divx/xvid movie is read as data over the IDE cable. then this data is processed by the playersoftware and send to the the right audio codec (e.g mp3), which sends its output to the soundcard driver, which instructs the soundcard (using the PCI or ISA bus) to make some noise. in the case of an audio cd: The cd-drive receives a "play" instruction for track 5 the cd-drive sends the audio it reads directly to the soundcard using the cable between the 2 devices. -- Bert Lagaisse K.U.Leuven, Dept. computer science Address: Celestijnenlaan 200A 3001 Heverlee Belgium Email: [EMAIL PROTECTED] Tel: +32 16 32 78 24 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

My understanding from the handbook was that I did not need to do this as I simply loaded a module (by editing the 'loader.conf' file). Am I mistaken? I am able to hear sound when watching films using mplayer. Does that not mean that the audio cable is connected to the sound card (in response to somebody's suggestion)?

Thanks, Rahul > Look at chapter 16 in the Handbook. There are some things that you have to do, such as add "device pcm" or others to your kernel before you can have sound. I have a black Lite-on in my test server and it worked just fine after I configured xmcd to use /dev/acd0c.

So that cable is necessary But he said it worked correctly under Linux, so that can't be it. Unless he was wrong and it *didn't* work correctly under Linux, of course. :) Cheers, Bernard ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Thanks, Rahul Maybe a common mistake: Is there an audio cable between the drive and the soundcard ? That is necessary to play cdda. I don't know the exact specs but your cd-drive sends the sound kinda "directly" to your soundcard. So that cable is necessary Greetz -- Bert Lagaisse K.U.Leuven, Dept. computerwetenschappen.
