 Posted: Tue Jun 16, 2015 4:16 am Post subject: automatic switch to hdmi audio output |
 |
|
all,
I'm trying to get alsa to switch audio output from my internal laptop speakers to the hdmi output. I was going to put in a udev rule to execute a script to make the change, but i don't get any events when I plug/unplug the hdmi cable. I am running the proprietary NVidia video driver. X notices the cable switch and sends video to the hdmi display land to my laptop screen appropriately. I can manually change my /etc/asound.conf, so I know that works too. What event can i capture to automatically switch the audio?

u have:
Support jack plugging notification via input layer (SND_HDA_INPUT_JACK)
in sound card -> ALSA -> HD-Audio
so maybe u can switch depending if jack is plugged or not.
