The audio jack on the front panel of my HP TouchSmart IQ770 is not working correctly in Ubuntu (9.10 and 8.04). When I connect a headphone or a speaker to the jack, Ubuntu plays sound in both speakers - the default integrated speakers and the newly connected device. Vista mutes the integrated speaker and switches to the connected device, which is the behavior I'm looking for. This is not a
9.10 specific issue because I had the same issue with
8.04 too (and I couldn't solve it then).
I tried manually changing the 'Connector' option to 'Analog Headphones' (from the default 'Analog Output') in
Sound Preferences|Output tab - but both the inbuilt speaker and headphones went silent.
I tried the workaround found here but it didn't work for me. I added
options snd-hda-intel model=hp (tried
model=auto too) to the
/etc/modprobe.d/alsa-base.conf but that didn't work either.
Here are some info that (I believe) might be required to understand the issue.
$cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.20.
$lspci //among other things 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)
$cat /proc/asound/cards 0 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xfbfb8000 irq 23 1 [SAA7134 ]: SAA7134 - SAA7134 saa7133 at 0xfebff800 irq 17
$/proc/asound/modules 0 snd_hda_intel 1 saa7134_alsa
Can someone help me fix it?
