Linux and S/PDIF audio.

post #1 of 53
Thread Starter 
Seriously, why is using S/PDIF so damn complicated? I've spent hours trying to get sounds from my computer and have gotten nowhere.

Things I've tried:

- Alsamixer
- Kmix
- Adjusted every slider in Alsa/Kmix at least 2 or 3 dozen times
- Tried muting channels
- Tried every sound configuration possible.

I should point out, I do have Analog sound but the onboard audio has zero bass and sounds like complete crap. Anyone have any ideas or things i can try?

Thanks,

Btw, I'm using Linux Mint 10 x64

So, you're getting sound, but it doesn't have the proper levels?

Do you have the proper driver for your sound card loaded?

Analog sound (the green port) yes, Digital sound (Coaxial port) no sound at all. The coaxial is going to a receiver with a digital audio port, then to the head phones. I run the same exact settings in Windows btw.

I'm pretty sure I do. I used the driver from Realteks site which is "406a".

Okay. can you run 'lspci' and post the output here? I'll see if I can't do some googling.

I'm at work right now, and imbedded images don't show up.

Is there a way you can get the text?

Your lspci output doesn't show a realtek soundcard, unless ATI is using a realtek chip.

I'll commence the googling either way =]

Okay. Now post the output of 'lsmod'

In windows I've had sound issues when installing a fresh version of XP/Vista or 7. SMBUS was highlighted yellow under Device drivers and I had to manually install the south-bridge driver.

After I installed the south-bridge driver for ATI SB400, I then installed Realtek WDM_4.06 and everything worked correctly. So I'm only assuming its something with the SMBUS (or southbridge) that's causing the issues, but being a complete n00b to linux I have no idea how to install/configure it.
