refer to hda specification 7.4.1 Standard Audio 48-Pin Codec Packages
1. PORT-A must have output capability. 2. If the codec has headphone capability, it must be available on PORT-A at a minimum. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/976076 Title: Can't switch between speakers and headphones Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: This is a freshly-installed Precise (from beta2 iso) on an AMD64 custom built computer; the motherboard is an ASRock N68-GE3 UCC, as you can see from the files the chipsets are all NVIDIA. The audio codec is VIA. Main problem: alsa and pulse's idea of switching between the speakers and headset is wrong. If I open alsamixer and toggle the (problematic, I heard) “Independent HP” switch, that works like a charm; turn it on and I get sound only on the speakers, turn it off and I get sound only on the headset. But nothing else (jack sense, clicking an output on Sound Settings, even muting “Front” by hand) works. Secondary problem: once that's working, it would be nice if jack sensing would do it automatically. I tried playing with the “model” flag and even “sense_mask”, but nothing works. I currently reset my alsa-base.conf to factory. I read many reports telling me to install the latest from ubuntu- audio-dev, but of course there aren't any for precise yet. Also installed some hda stuff from diwic; hda-jack-retask reports my front pin is a green headphones front pin as it's supposed to be, so I didn't override anything. And hda-jack-sense-test calls it “Green HP Out”; but only lists it with -a. lalo:~> sudo hda-jack-sense-test -a Pin 0x24 (Green Line Out): present = Yes Pin 0x25 (Black Line Out): present = No Pin 0x26 (Orange Line Out): present = No Pin 0x27 (Grey Line Out): present = No Pin 0x28 (Green HP Out): present = Yes Pin 0x29 (Pink Mic): present = No Pin 0x2a (Blue Line In): present = No Pin 0x2b (Pink Mic): present = No Pin 0x2c (Internal CD): present = No Pin 0x2d (Not connected): present = No Pin 0x2e (Not connected): present = No Pin 0x2f (Not connected): present = No ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-22.35-generic 3.2.14 Uname: Linux 3.2.0-22-generic x86_64 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
