In RedHat7.1 all is well, I can play music, r/w data, and use cdrecord ... however, in Libranet (debian) ... I can access my dvd and cd-rw drives as cdroms (data) but not play music through the speakers, although the cdplayer software shows song playing progress and song names, and headphones are working on the cd-rw. My mistake was trying to add scsi support for the cd-rw, to allow cdrecord. This failed for some reason, so I tried to backtrack and ended with no sound from music cd's. ARghh! Unfortunately, I love Libranet, much preferring it to Redhat. -- Ken Moffat [EMAIL PROTECTED] _______________________________________________ Linux-users mailing list Archives, Digests, etc at http://linux.nf/mailman/listinfo/linux-users
