Hi all. I have gentoo running on my Sony PCG-V505EC. Pretty much everything works great. My only problem is CD sound ... I have none.

What I mean is, if I play a CD "directly" using KSCD or xmms, there is no sound.

But if I play a CD "through" a digital interface, conversion to ogg for example and playing through kaboodle or xmms, the sound works fine. All digital sounds work fine (KDE sound effects, Gaim sound effects etc).

Any ideas?

Mark

yea, been there. unmuted everything, turn all volumes up. Thing is, shouldn't the CD be playing direct to the speakers? In my desktop PC, the CD player is connected directly to the sound card so if I play a CD, it can be played "direct" to the sound card, with no OS intervention, or I can optionally play it through some digital channel, say conversion to ogg on the fly, which does involve OS intervention.

You could try the xmms plugin to read cd as data.

It is handy if there is no cable direct from the CD drive to the soundcard.

Code:
emerge xmms-cdread

Curiously enough, I thought I would try playing an audio cd on my machine - it's not something I have done in quite a while, what with encoded music and internet radio....
Anyway, I am suffereing the same problem, I use Grip, it thinks it's playing the CD but I can't hear it.
If I wind up xmms, I can play digital sound...
Hmmm...
I will have to check if audio plays under windoze... just in case... It's been a while, the actual machine has changed a bit...

All I get out of xmms-cdread is static.

Yea. Who'd of thunk just playing a CD would be such a pain. I mean, I can play the CD through a digital channel, but I'd rather play it direct.

So to top it all off, analog play works just fine from within Windows. WMP allows you to switch between analog and digital play, and both work. But analog play does not work in Linux.

Xmms works the same ... the CD plugin allows you to switch from analog to digital audio. But in this case, digital works, while analog does not.

Maybe I am missing something in my kernel? Something under /dev? Maybe device perms?

Code:
