The functionality you are asking about may not be supported in the gentoo-sources or vanilla kernels yet. I found this, though, which may be pertinent: http://forums.gentoo.org/viewtopic-p-6451622.html?sid=3f427246ce85b07753b1aa8bd7694685#6451622 So it's a kernel issue, right? I just didn't know if it's a kernel, alsa, or something else. Should I go to the kernel bugzilla with this instead? The forum post mentions support in alsa 1.0.23. Alsa in 3.1.4 is at 1.0.24. Can you please test with the latest gentoo-sources as of this writing to see if any progress has been made. The latest gentoo-sources is now at 3.1.5 Just checked the 3.1.5 gentoo-sources. Still the same. After some more tests, it turned out that technically, the LED does work: I can activate it manually with HDA analyzer by switching on flags "enabled" and "dir-out" on GPIO IO[0]. As I got it from changelogs, GPIO0 is chosen by default as a mute led if there is three or less GPIOs (I have three). Still don't understand why it's not like that in my case. May be I should provide some model name to the kernel image? Please test with vanilla sources 3.2.9 and then bring to https://bugzilla.kernel.org/ if it still fails. Please post the url back here. Issue is solved by enabling CONFIG_SND_HDA_POWER_SAVE. |
