Disabling broken headphone jack

I own an Acer Extensa 4620z laptop with Intel Corporation 82801H (ICH8 Family) HD Audio Controller for my audio output.  I had broken the headphone jack a while back, and have typically been bypassing this problem with an external Behringer UCA202 USB soundcard.  The computer consistently believes there are headphones plugged in, and only currently outputs to the broken jack.  Arch recognizes the card, but unlike other distros isn't really letting me set a specific preference to the UCA as opposed to HDA-Intel.  I am using ALSA without any OSS.  The system lets me order the priority of audio devices, but does not seem to actually route the audio output to the USB card.

I am not sure what to post that would be relevant in config, but I am happy to provide any info recommended.

Could you paste your ~/.asoundrc if it exists? Sounds like you just need to set a default card in there.
Here's an example:

pcm.!default {
    type hw # Kernel PCM
    card 1 # Card name or number
}

You can also blacklist the soundcard module:

Re: Disabling broken headphone jack

@mrhmouse: the file is completely blank. I am now looking into configuring asoundrc, but any recommendations are nice.

@Pajaro:  Is it capable of blacklisting specific components of the hardware though, or just all of HDA_Intel?  I know it's picky, but at times it'd be nice for the speakers to work, just wish to disable any headphone output.  In relations to my UCA202 working, I guess the blacklisting would work well... I'll look into it.

Re: Disabling broken headphone jack

blacklisting the module would make the soundcard inexistent.
