Laptop and music cdrom

[panther]

After a lot of troubles I have fixed my cdrom problems

but I am not able to play music cdrom

I have an inspiron 8200 dell laptop so the extra wire solution is probably out of question, I am using gentoo and Alsa.
And I am not trying to mount the cd. XMMS ir KsCD will start but they do not play the music

Do you have any suggestions?

Also when I play dvd through xine I do not have audio output

Perhaps alsa is not for my system?
Any ideas any suggestions?

Check your volume settings (alsamixer if your using ALSA) and make sure nothing is muted (off)
I think Xine uses PCM for the audio, make sure that is unmuted and turned up

I discovered this on my laptop also, but haven't had time to figure it out (trying to get sound working with the 2.6.6 kernel, some reason it doesn't work)

Also, make sure that the /dev (/dev/hdc on my dell 8500) that /dev/cdrom points to has the appropriate permissions for you to use it... I just had to fix this in Debian...

thank you all for this!!!


But I have unmute all the channels

and I have taken care my /etc/fstab

still the same problem

just to make sure I had used the commands

amixer set Master 100 unmute
amixer set PCM 100 unmute

in fact

it seems that the music cdrom it does not recognised by the appropriate programs either.

this is only for music cd-roms

actually see what the permissions are for /dev/hdc (or whatever your cdrom drive is linked to)... I had to change /dev/hdc to the audio group before my sound would work... or to see if it is a permission problem you could try and play the cd as root... which I was able to do before I changed the permissions on /dev/hdc. Changing the group may not be considered the best way to deal with this (I have no idea really) but it worked for me.

I am logged as root

it does not work I am afraid

this is my fstab

NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda6 /boot reiserfs noauto,noatime,notail $
/dev/hda8 / reiserfs noatime,notail $
/dev/hda7 none swap sw $
/dev/hda5 /mnt/data vfat umask=000,auto,users $
/dev/hda1 /mnt/xp ntfs umask=000,noauto,users $
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro,users $
/dev/fd0 /mnt/floppy auto noauto,users $

shouldn't this :

/dev/cdroms/cdrom0 /mnt/cdrom

be something like this:

/dev/hd(x) /mnt/cdrom

I think this should have changed when you set up your gentoo fstab during installation... I remember having to change mine on gentoo to

/dev/hdc /mnt/cdrom
or
/dev/cdrom /mnt/cdrom

(can't remember which one) to get audio to work... at any rate, it's worth a shot... and you can always change it back.

I have play with changes in the /mount/cdrom

but I must admit I have not with hdc

I presume this would creates hard links etc,

My laptop does this too.

I've checked all the mixer channels in aumix (ali 5451 sound chip), etc, and nothing seems to make kscd work.

There is a workaround, though. Go to xmms prefs, and hit "configure" for the cd audio input plugin. Change the play mode to "digital audio extraction".

Your cd's should play in xmms. Now instead of going through the CD drive audio path ("Hey! /dev/cdrom! Play track 3!), xmms reads the 1's and 0's off and does the audio manipulation itself. ("Hey! /dev/cdrom! Start reading bytes off to me, starting here! I'll figure out what to do with them.")
