View Full Version : [SOLVED] Audio problems with Asus N71/Intel HDA

March 5th, 2011, 12:58 AM
Howdy Ubuntu community. I recently decided to switch my laptop (Asus N71Jq) from Windows 7 to Ubuntu only, committed to finally familiarizing myself with GNU/Linux. I installed Ubuntu 10.10 64-bit, but have been struggling for the past couple of days to get the Intel HDA sound controller working fully.

After a fresh install of Ubuntu 10.10, the speakers, headphones jacks, and microphone jack all work great. The only problem is that I can't record from the internal microphone. I can listen to it by unmuting the mic using a mixer, but all recording applications like arecord only pick up the microphone jack.

I can get both microphones working properly if I add "options snd-hda-intel model=auto" to the /etc/modprobe.d/alsa-base.conf file. This however breaks one of the two headphones jacks, and makes it so the tiny subwoofer on the bottom of the laptop to not mute when headphones are plugged in. I've tinkered with all the other model settings, but auto works the best.

Essentially, it would be nice if I could combine the output channels of the default setting, with the input channels of the model=auto setting. The laptop uses an Intel 5 series chipset, with Intel HDA audio, using the Realtek ALC663 codec. If anyone has any advice for me, I would really appreciate it.

Here's the alsa-info.sh outputs using each of the two settings:

Here's a screenshot of the mixer using the default settings, without the model=auto line. The only recordable line is the Capture line. It however only picks up the Mic line, not the IntMic line. I can only listen to the IntMic line.

I still have not gotten anywhere with this issue. If anyone has any ideas, I'd appreciate it.

Hi CYcolone,

I have the same problem. Have you found a solution? Either I can't use the microphones or it sounds like a tin...

Found this model options (http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt) , but hadn't time to test them all:
