From /etc/modprobe.conf: <snip> alias snd-card-0 snd-intel8x0
Happy Birthday to me! My wife couldn't stand me whining about my old machine, so she picked up a demo emachines for my birthday from Best Buy. I just finished installing fedora core 3, and I'm having a few problems with the audio. 1. The audio test worked fine during the installation, and the "soundcard detection" menu pick still works fine. 2. When I play an audio CD, I have a couple of problems. a. There is no /dev/cdrom device. I made a sym link, but that disappears during reboot. What's the right way to get it in place & stay? b. The permissions on the cd player (/dev/hdc) are 600. I changed them to 666 so I could use the player, but, like the symlink (above), this change does not survive the reboot. Again, what's the right solution? Once I do a & b, then I can see that the cd is playing. With "grip", I can see that it's even getting the names of the tracks. Very cool. 3. No sound. I've played plenty with gnome-volume-control, but no sound. I don't even get anything from the headphone jack on the front panel.

Is there a /dev/cdrecorder or similar? Something like this should have been created automatically by the scripts in /etc/udev.d. I think you can force manual creation of device nodes my mucking about in /etc/udev.d, but I haven't tried it yet.
b. The permissions on the cd player (/dev/hdc) are 600. I changed them to 666 so I could use the player, but, like the symlink (above), this change does not survive the reboot. Again, what's the right solution?
The owner of the device(s) should be set automatically by pam/consolehelper when a user logs into the console/GDM. This is set in /etc/security/console.perms.
3. No sound. I've played plenty with gnome-volume-control, but no sound. I don't even get anything from the headphone jack on the front panel.
Are you playing the CD with Analog output, or Digital Audio Extraction output? If you are using the former, you might not have an Analog audio cable between your CD drive and the sound card. This is becoming common on newer machines (one less cable == cheaper). Try telling the CD player app to use the Digital method instead. Finally, make sure the channels are unmuted and turned up. It may be as simple as finding the CD slider in the volume control and turning it up (for Analog).

No need to change the permissions to 666. See, you own the device, being the currently logged in console user.

Where do I find this (the setting to use digital rather than analog)? I gave a quick look at the user controls & did not find it. I inspected the hardware, and you're right -- no audio cable. Maybe the solution is to just get that cable. (?)

I had already tried this with no results. Thanks, Bill

Oh yeah, the "CD Player" app in GNOME doesn't support it. I used XMMS instead, whose cd input plugin supports Digital audio extraction.

If there is a place to plug it into the soundcard (onboard I presume), then yes, that would solve the problem too.

I've always found xmms to be non-intuitive for playing CD's -- I just can't seem to get it to see the CD. I found an audio cable & that fixes the "standard" audio apps. (The only thing I'd like is the equalizer from xmms, but that's just to play with it.) Thanks, Bill
