Comment 23 for bug 218165

I tried this workaround on a Acer Aspire 6920-6141 and it make the sound work on the internal speakers, but that's all...

The headphone jack is not working. I can't mute all the speakers and get sound in the headphones (I tried all possible model param to the drivers and got nothing). The tuba always stay on as long as front is on and if I turn front off the headphones are turned off too.
