optiplex gx620 sound switching
« on: April 30, 2011, 01:32:32 PM »
Hi,

My desktop has built in speakers plus a headphone jack. When I put in headphones, it continues to play through both speakers...Is there a way it can swap? When my headphones are in, play via those only? I tried playing with pulseaudio and didn't get anywhere.

The only thing that sort of works is if I set the "pcm" channel low while the headphones to max, I only hear through the headphones...Any other way?

Thanks!

add -- options snd slots=snd_hda_intel,snd_usb_audio -- to your /etc/modprobe.conf file (as root)

Possible solution, plus open your mixer channel settings, move all options from the left to the right, on by one, all sliders to the max.
Testing.

Hope this helps ;)

Hi,

Editing modprobe just disabled all my sound so I commented it out.

By setting pcm to minimum and headphones to max, it works ok...however, the sound volume through the headphones is quite low.

It seems that it's not correctly interacting with the hardware....

Here's what I ended up doing.

1) Make sure pulseaudio is disabled (and then possibly reboot if you disabled it)
2) Open a terminal and type alsamixer
3) Scroll over to "Headphone Jack Sense".
4) Switch it from "MM" to "00" by hitting M.
5) Use PCM as the main in mixer. It will now switch automatically.

I hope this helps someone!
