I just put Slack 8.1 on a laptop, but there are some CD & sound issues.

When I try to use the CD player, I get the message:
"Error accessing cdrom device. Please check to make sure CDROM support is compiled into the kernel, and that you have permission to access the device.

I am able to mount and browse a data CD, but I can't play an audio one

I also notice that when applications like Gaim try to BEEP or make a sound, the following message arrives on stderr:

/dev/dsp: No such device

further investigations such as $ cat /dev/audio > bla dies with:

/dev/audo: No such device

But

bash-2.05a# ls -al /dev/dsp
crw-rw-rw- 1 root sys 14, 3 Jul 18 1994 /dev/dsp
bash-2.05a$ ls -al /dev/audio
crw-rw---- 1 root sys 14, 4 Jul 18 1994 /dev/audio

Is there a sound card configuration tool/file that I can use?
any ideas guys?

Christo

are you tryin to mount the audio cd, coz every time i mounted a cd it wouldnt let me, I then fund out that audio cd's do not need to be mounted

for the sound card issue chmod /dev/audio to 755
and do the same for /dev/dsp and see if that works

Both of these are pretty normal default installation problems with Slackware. Slack doesn't configure sound for you at all.

/sbin/lspci

and that will tell you the type of soundcard you're using, so we can figure out what module you need to load.

chmod 666 /dev/cdrom

will take care of the CDROM problem as users don't have access to the raw device by default, but root does.

Thanks for the guidance.. I opened up the permissions on /dev/cdrom and it now reads a CD fine...

But it's all very quiet, due to a non-configured card... er here's my output from /sbin/lspci. I guess we're looking at the Allegro-1 bit, yes? So maybe all I need to do is modprobe something...

modprobe maestro3

That should be the right driver. In /etc/rc.d/rc.modules, either un-comment the line for the module, or much more likely, just create one as the list is far from complete.

Also, in order to get sound as a user you're probably going to have to chmod 666 /dev/dsp also. It might bitch about no mixer too, same deal... just a few Slack set-up quirks.

Compaq right? You got lucky having an S3 card, I've got a bloody Trident (closed spec twerps), can't get any of the accelerated graphics modes to work.

Finegan,

we are so nearly there...

I probed out the module and it plays CD's fine now.. and yes, I can hear them!! I can also run XMMS no probs.. ah, Slack ain't looking so bad afterall However, when I try to run mpg123 asong.mp3, I get a new error:

/tmp/mcop-christo is not owned by user

christo is the username running mpg123

have you seen this before?

thanks for your help,
Christo

Nope... That's a little weird... I think, but I'm not sure, that something else is currently laying claim to the sound device. If the CD player, especially KDE's which is very barebones, is currently open then some of the other barebones utils like mpg123 and amp grouch.

My poorly educated guess is its just a lock file. Something might be temporarily weird from the chmod fest too... if killing X entirely doesn't cleanse it, then a reboot should.

Luck,

Finegan

I'll have a fiddle and post back later.

thanks so much for your efforts

christo
