I have a Gateway NV52 series laptop which refused to enable the internal mic. Email Required, but never shown. The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa. Eventually, I pressed Esc to end alsamixer and save my changes.

Consequently, an HDA motherboard would not detect the presence of an AC’97 dongle with a disconnected pin 4. On the other hand HD audio cables have a wire and terminal connecttor lurking there, waiting silently in that cold dark hole poised and ready for the time when a naive unsuspecting pin 4 who isn’t even old enough to leave his motherboard slips into the High Definition Audio clutches of that extra wire.

Post as a guest Name. When a plug is inserted, the stereo signals contact the respective channels on the plug and are disconnected from the jack’s return pins. It’s probably as well a labeling issue. Your particular front panel looks to me like it is primerally designed for HD audio motherboards but with a hack to give limited support for AC97 boards.

High-definition television High-definition video Ultra-high-definition television. It is recommended that you look at your motherboard manual.

I will be adding emphasis. In AC’97, pins 2 and 4 are audio ground, but pin 4 is often disconnected. Consequently, a loud audio passage may make the HDA motherboard with AC’97 dongle believe that headphones and microphones are being plugged and unplugged hundreds of times per second. I too had a problem with mic not working with playback OK, and it turned out that probably due to model mismatch in snd-hda-intel options the capture volume controls were mislabeled and the slider that was responsible for the microphone was the one with “Digital” caption.

Features of the specification include: However, as of [update]most audio hardware manufacturers did not implement the full specification, especially bit sampling resolution. I then booted ubuntu 7. The configure script is unable to find the autoconf. Adding this as a comment in case someone comes across it.


This apparently seems to be for systems with non standard HD audio implimentations. Eventually, I pressed Esc to end alsamixer and save my changes. Page History Login to edit. Retrieved 14 January Sign up or log in Sign up using Google.

Checking this forum post and this guideI’ve managed to get a configuration that seems to work fine. When the plug is inserted, the isolated switch inside the jack informs the motherboard, and the asalia sends audio to the headphones.

I would suggest trying the HD audio connector first, if the rear audio output on your motherboard doesn’t work try using the AC97 connector instead. To enable the microphone, I had to select “Mic” and not “Front mic” in the option tab as ajdio capture device.
