SOLVED: Speakers not muted using headphones on Lenovo SL510 running Tumbleweed

English Install/Boot/Login

Lenovo SL510 notebook’s speakers are no longer muted when headphones are plugged in. This is on a Tumbleweed system fully updated as of yesterday, with kernel-desktop-3.0.3-41.1.x86_64. Problem also occurs with previous kernel-desktop-3.0.1-40.1.x86_64.

IIRC, the problem wasn’t there using kernel-desktop-3.0.0-39.1.x86_64 but cannot verify as it’s no longer installed here. Noted from zypper’s history that ALSA library was updated to libasound2-1.0.24.1-22.1.x86_64 a couple of days after kernel 3.0.0-39.1 was installed.

There were no problems on previous version-2 kernels on Tumbleweed, and muting of speakers works properly on standard openSUSE 11.4 (version-2 kernel).

Sound chip: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
Codec: Realtek ALC269
ALSA module: snd_hda_intel

Following a recommendation from @oldcpu in this other thread, I solved the problem by adding this additional line to the beginning of /etc/modprobe.d/50-sound.conf

options snd-hda-intel model=laptop-amic

Available model options for ALC269 (and other codecs) are documented in /usr/src/your-kernel-version/Documentation/sound/alsa/HD-Audio-Models.txt

I also tried with model=basic and model=auto, but those options failed to solve the problem.

Thanks for sharing your solution for your Lenovo SL510. Speaking of Lenovo’s, my wife ordered a Lenovo X220 netbook, which arrived at my sister’s in Regina Canada to days ago. My sister will be meeting us in Vancouver Canada on Friday this week, giving my wife the netbook then, and then later in September we will bring it back to Germany (paying the VAT at the airport upon arrival). I’m curious to see what (if any) tuning I will need to do with openSUSE GNU/Linux on that Lenovo X220 netbook wrt sound. The recent packaging of an equalizer for pulse audio has IMHO significantly improved the sound quality one can get with a laptop/notebook/netbook as of openSUSE-11.4 and newer.

lol ! …

Actually, no, we will make a point of paying the 19% VAT at the airport, as we need the receipt from that for Income Tax return purposes.
