After compileing my kernel i get no sound.
I tried :
alsaconf - choose my sound card - everything is all right, but when i try alsamixer i get :
No mixer elems found

lspci:
01:00.1 Audio device: ATI Technologies Inc Device aa38

lsmod:

snd_hda_codec_atihdmi 1747 1

soundcore 3923 1 snd
snd_page_alloc 4997 2 snd_hda_intel,snd_pcm

When i compilied the kernel i added the modules : HD Intel... any ideas?

I'm running something similar and here are my details:

This may help (or not

2 observations.

a) This is the hdmi audio output that your gpu can provide.

Code:

01:00.1 Audio device [0403]: ATI Technologies Inc RV710/730 [1002:aa38]
        Subsystem: ASUSTeK Computer Inc. Device [1043:aa38]
        Kernel driver in use: HDA Intel

In the same way, mine is

Code:

01:00.1 Audio device [0403]: ATI Technologies Inc Radeon HD 3870 Audio device [1002:aa18]
	Subsystem: ASUSTeK Computer Inc. Device [1043:aa18]
	Kernel driver in use: HDA Intel

In my setup, this audio "card" lists as "HDA ATI Hdmi" in alsamixer card selection dialog, and it's the 2nd (as in secondary) card for my system. The 1st (as in primary), which is identified as "HDA Intel" in alsamixer, is

Code:

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)
	Subsystem: Giga-byte Technology Device a002
	Kernel driver in use: HDA Intel

b) I assume your user is in the audio group already...

@jim_p Whoops. I think you're mixing me up with the OP. I'm not the one with the problem. My sound system works fine. Check the 1st post for RPAngelov's specs.
