No Audio on Jack Sense With ALC202 Audio Chipset

Bug Description

On my laptop (Acer Travelmate 270) the sound stops as soon as something is plugged in to the headphone jack. The external speakers are disabled as expected but so is the audio supplied to the headphone jack.

If the headphones are only partially insetted (enough to make a contact but not to trigger the jack sense) both external speakers and headphones work. The socket and headphones work as expected in windows.

There is no entry in the ALSA mixer for Jack Sense to allow it to be disabled (like many laptop chipsets have).

The laptop uses the Realtek ALC202 Audio Chipset, this is provided by SIS under the SIS961 model number. I am not sure if this problem is present in all ALC202 impletmentations, just the SIS961 implementations or just the Acer Travelmate 270.

Either way it makes the machine pritty usless for anything involving sound as the internal speakers are so bad.

This occurs on Ubuntu 6.06 LTS (Dapper Drake).

Does muting 'IEC958' and 'Aux' give you audible sound again?

Muting 'IEC958' and 'Aux' appear to have no effect.

It is stil fine using the external speakers but as before plugging anything into the Headphone jack socket stops all audio output from the internal speakers as well as the Headphone Jack socket itself.

Thank you for your asistance so far, do you have anymore suggestions.

Sorry I just noticed a major typo in my last post. The second para should read.

Unfortunately I never found a solution to this problem. My solution
was to use another computer with a different sound chipset.

If you do find a solution I would be grateful if you post it back to
this thread.

Sorry I can't be of anymore help.
