I am having trouble with some of my sound apps.  I can play CDs MP3 with

Erm, just a guess, but maybe AlsaPlayer, etc. are using the ALSA sound system, whereas Rosegarden etc. are trying to access the sound card directly? They won't be able to do that, because ALSA is using it (and only one program can access the soundcard directly at any one time).


If that is the problem, I can think of three possible solutions. The most elegant would be to get Rosegarden etc. to use ALSA (they might have an output plugin or option somewhere). The less elegant option would be to stop ALSA from running. KDE has a control panel section for it, or type "/etc/init.d/alsa stop" into a command line. A slightly nicer bodge is to set ALSA to give up control of the soundcard after a certain period of inactivity.

The third option is to use the artsdsp 'wrapper' (eg. type "artsdsp rosegarden"). This fools the program into thinking it's accessing the sound card directly, but actually it's talking to the sound system. I've never had much luck with this, it always seems to make XMMS crash, but your milage may vary.

Hope this helps.

Cheers,

Jon

The usual advice on this stuff is that there is no output cable connecting the cd drive to the sound card as most PC manufacturers don't bother. I had a similar problem with xine playing CDs, but kcd not (though it recognised one was loaded). Dunno just a guess...
