I cannot get xmms to play an audio cd using its Oss Output Driver in Digital Audio Playback mode. However, I can manually move the slider and get xmms to play a few notes but that is all.

If I switch the Disk Writer Output Plugin, xmms can write cd audio tracks to .wav files on my HD & these .wav files can be burned via cdrecord & played back on a standalone cdrom player -- but not by xmms on my computer.

Xmms also has a problem playing sound files from the /usr/share/sounds directory. Long sound files like the k3b_success1.wav are only partially played back. Again,---if I manually move the xmms slider I can here a different section of the file.

Now, if I configure the xmms Oss Output Driver for "Analog Audio Playback" mode, the xmms slider moves, the cdrom drive activity lite blinks and everything appears to be working properly but no sound is heard. I think I need to have a cable running from the cd drive to my onboard sound connector.

I would like xmms to play cd's in Digital mode Can anyone help?

In the meantime I am going to call around an see if I can locate the proper cd to sound-card cable.Maybe my system can only play cd's in Analog mode. Besides, I'll never know if the xmms analog mode is really playing sounds in analog mode or if is just going thru the motions until I connect the analog cable.

Thank you for taking the time to read this.

what distro are you using? do you have libcdaudio, wave player, etc.? ("locate libcdaudio.so" "locate libwav.so"). are the plugins enabled in the xmms Audio I/O Plugins screen (in Preferences)? any particular reason why you are using OSS? have you tried alsa, or do you have it installed, configured in the kernel, etc. (why i ask which distro ).

I am using Mandriva-2006 Discovery & I do have CD Audio Player, & Wave Player input plugins enabled. I also Have both the OSS & Alsa output plugins but originally chose to use Oss because it sounds out a few more notes than Alsa when I play a simple .wav file off the HD. ...... I have since changed to the Alsa output plugin

By-the-way, I located and installed a 4-pin analog sound cable from my dvd-rom drive to my Asus MB & now I can play music CD's while in "analog" mode but I still can't play music .wav files off the HD in "any" mode. Digital output by xmms is also still not functional on my dvd-rom & my dvd-rw drive if I configure xmms to use digital mode

It isn't just xmms that has trouble in digital mode Here are some other things I tried:

xmms ..... no sound with .wav file
xmms ..... plays a few note if slider moved manually
/var/log/messages: kernel: zero position is read

cdda2wav dev=/dev/hdd -q -e -t3 -N ..... no sound

cdda2wav dev=/dev/hdd -O wav -H -t 3 track3.wav ..... writes a functional .wav file

cdparanoia -d /dev/hdd -3 - ..... no sound

Special Note:
Xine will play a commercial dvd video disc "with sound" from my dvd-rom drive but only if I load the OSS sound driver via82cxxx-audio & configure it to use OSS instead of using Alsa & its corresponding snd_via82xx driver. This is digtal sound output isn't it ??? I don't think xine even has an option for analog audio playback.

Now, If I try to play an audio cd with xine "no" sound is heard & /var/log/messages displays:

kernel: playback write error (DMA or IRQ trouble?)

Thanks again for reading this rather long reply post. I'd appreciate any suggestions.

i wonder if it's an alsa problem with A64 and VIA? you might try searching the alsa buglist or LQ or google to see if you find any information. you ran alsaconf right?

You were correct in thinking my xmms digital sound problem was a bug. Here is a copy/paste of what I found at alsa. It sounds like this bug has been fixed but the bug report doesn't say what was done to resolve the issue.

I assume Alsa will issue some sort of patch & future releases of both the alsa driver pkg. & linux kernel modules will incorporate the bug fix. I'll poke arround a bit more at the alsa site but my browsing & search skills are pretty limited If anyone knows the alsa procedure, I'd appreciate a brief explaination of what happens. Thanks to all of you.
