Public bug reported:
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).
