! Truoble with play SCSI Emulation and CD Rom!

Fabio_Giovagnini · June 27, 2001, 7:40am

Hi,
I’m trying to write a little test application for mai CD-ROM. It is a
CD-Writer so I have to use SCSI emulation to use CD-record. Good, when I use
SCSI emulation I’m not able to start SDL_CDPlay(): the software say
everything works but I can’t listen anything.

Any Ideas?

Thanks.

Have you tried playing a CD in any other programs?

If it doesn’t work in anything else either then open up your computer and check that there is a cable running from the back of your cdrom to your sound card.
I am pretty sure this is needed when you play music direct from the CD.

without SCSI emulation option everything works good, so I’m sure the cable
is connected.
Thank you.

Which operating system?
Win32 CDROM driver in SDL does not work with Win2k or WinME. It should be
updated (that’s in my personal SDL todo list)—

Does the CD-ROM spin up as if it were playing when you call
SDL_CDPlay(), but doesn’t output any sound? Or does the disk do nothing
at all?
You DID call SDL_Init(SDL_INIT_CDROM), right?
You DID call SDL_CDOpen() and SDL_CDStatus() before playing a music
track, right?
There were no errors reported by SDL_Init(), SDL_CDOpen(), or
SDL_CDStatus() before you tried to play a music track, right?
You aren’t calling SDL_CDPlay() when you really mean
SDL_CDPlayTracks(), right?
There’s nothing else trying to use the CD at the same time (like
X-CD-Roast) sitting in the background, right?
Are other programs on your system (xmms, grip, etc) capable of playing
CD audio when you are using the SCSI emulation?
What kernel version are you using?

I just tried a quick-and-dirty SDL program here, and it could play CD
audio, and I’m using SCSI emulation, too.

The program I wrote is here:
http://www.icculus.org/misc/testsdlcd.c

Download that, compile it:

gcc -o testsdlcd sdl-config --cflags sdl-config --libs testsdlcd.c

run it:

./testsdlcd

…and let me know if it works. Then we can start debugging.

Thanks a lot. I needed a so deep explanation. I’ll do everything and I 'll
give you informations.
