Hi, After updating to gentoo-sources-3.9.0, alsa lost the mute function. The sound is still functioning, so I can volumn up and down, but no morm mute. I reuse my old .config from kernel 3.8, did not make any major changes. Reproducible: Always Steps to Reproduce: 1. amixer -c 0 -- sget Master 2. 3. Actual Results: Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined Playback channels: Mono Limits: Playback 0 - 74 Mono: Playback 0 [0%] [-74.00dB] Expected Results: Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 74 Mono: Playback 0 [0%] [-74.00dB] [on] (as in kernel 3.8) I found there are two differences, the first one is "pswitch pswitch-joined" are missing from the Capabilities, and the second is there is no "[on]" from the Mono field. I know there are some major changes to alsa in kernel 3.9 [1], I just wonder whether this is my problem or it is a kernel bug. [1] - http://www.phoronix.com/scan.php?page=news_item&px=MTI3ODE

My laptop is Lenovo T400. I am unsing modprobe to load alsa module with following options: - snd_hda_intel enable_msi=1 - snd_hda_intel enable_msi=1 model=thinkpad - snd_hda_intel enable_msi=1 model=idlepad but none of them worked.

Same here on a Lenovo ThinkPad T400 with ALSA driver in the kernel (not as module)
Is this related to bug 468690? There is a patch to test.
That patch does not solve the issue. I have upgraded the following two packets =media-sound/alsa-utils-1.0.27.1-r1 =media-libs/alsa-lib-1.0.27-r2 The issue is still persist.
Please try upgrading your bios to at least 3.1, or pass the string acpi_osi="Linux" to the kernel as a boot parameter. Let us know which one you try and the outcome.
i have simular problem, after upgrade from 3.8.13 there is no more speakers and headphone volume selectors and after hibernation there is no sound from speakers. http://paste.kde.org/p2e3fbf74

Please try the above; besides that, try a more recent kernel: 1. =sys-kernel/gentoo-sources-3.10.6 (Upstream latest stable kernel) 2. =sys-kernel/git-sources-3.11_rc5 (Upstream latest development kernel Thank you very much in advance.
