I've noticed a few messages (on various lists) about problems playing
audio CD's. Just another data point, if I try to play to audio CD's on
a Toshiba 4101 (connected to an Atari), I get :
cd0(ncrscsi0:6:0): Check Condition on opcode 0x15
SENSE KEY: Illegal Request
ASC/ASCQ: Invalid Field In Parameter List
SKSV: Error in Parameters, Offset 25, bit 7
but the CD plays. My NEC drives (sparc/i386) won't play at all and my
Pioneer drive (sparc) plays with an SCSI error.
The problem appears to be with the CDIOCPLAYTRACKS ioctl . I've had a
quick look but I'm not sure why 'Offset 25, bit 7' is incorrect. The
smallest program that I can generate the problem with is :
#define CD_PART "/dev/cd0c"
struct ioc_play_track cmd;
cmd.start_index = 1;
cmd.end_index = 1;
cmd.start_track = 1;
cmd.end_track = 1;
d = open (CD_PART, O_RDONLY);
ioctl (d, CDIOCPLAYTRACKS, &cmd);
Any pointers on where to look?
PS. This came up on port-sparc originally, but it doesn't seem to be port
 AFAIK xmcd doesn't use CDIOCPLAYTRACKS, so that's why it works but
xcdplayer et al. fail.
