Subject: [gentoo-user] No sound. Please, help!

1 At different times during the last one and a half years, I tried to
2 make sound work on my new Gentoo install on a computer with Gigabyte
3 GA-MA790FXT-UD5P motherboard and MSI ATI Radeon R4770 graphic card.
5 Previously, I successfully solved the sound problems in Gentoo either
6 with alsamixer or by compiling the right driver into the kernel but on
7 this computer these two approaches failed so far.
9 In my penultimate attempt to solve this problem, I spent no less than
10 one week trying to compile the right driver into the then 4th Linux
11 kernel with no result. At the beginning, I managed to get a sound from
12 this computer after some kernel configurations but they turned out to
13 be unstable in the sense that later the same kernel configurations
14 resulted in no sound. (I have used git to control all my experiments
15 with the kernel configurations, so I am quite sure that configurations
16 of the kernel for which I sometimes got the sound and later did not
17 was indeed the same.) My first explanation to this phenomena was that
18 after recompiling a kernel I also have to recompile xorg-server and
19 some sound related packages. So I have tried this with no result
20 again. And, of course, I have always used alsamixer to make sure that
21 no sound channels are muted.
23 Finally, I decided that I just cannot find the right combination of
24 sound drivers and gave up because at that time I could not spend on
25 this more than one week.
27 But last month I found out about the gentoo-kernel package and decided
28 to try once more. I was almost sure that, after installing this
29 package, I will finally get the sound. So, I have installed the
30 latest, 5.4.64, version of this package. As a result, the computer
31 rebooted in the new Linux kernel and everything worked and still works
32 like a charm except for the sound as it is still absent. :(
34 So I definitely (and desperately) need your help and promise to follow
35 all your suggestions. (But, please, take into account that I can
36 compile on this computer only during weekends.)
38 As the following command shows
40 lspci | grep "Audio"
41 00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00
42 Azalia (Intel HDA)
43 01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] RV710/730
44 HDMI Audio [Radeon HD 4000 series]
46 This computer has two sound devices. The first of them, SBx00 Azalia,
47 is probably built into the motherboard, and it is where I am trying to
48 get a sound from. The second one is probably built into the Radeon
49 graphic card and I am not going to use it at all unless it can output
50 the sound through the motherboard audio jacks.
52 My current kernel configuration is exactly the same as in the
53 gentoo-kernel-5.4.64 package as I have not changed anything there.
55 And finally: installed on the same computer legacy operating system
56 never had any sound problems.
