Alsa set default audio device

Everytime I used my webcam, the default output device gets set to microphone of the webcam on reboot.

I followed the wiki: https://wiki.archlinux.org/index.php/Ad … sound_card

The device list:

cat /proc/asound/modules
 0 snd_usb_audio
 1 snd_hda_intel
 2 snd_hda_intel

the "2 snd_hda_intel" is hdmi audio output from nvidia graphics card.
I want to set "1 snd_hda_intel"  as my default device for output and "0 snd_usb_audio" as input default.
Issue that I have with setting default alsa device is nvidia and onboard card having same name.
Is it possible to set the default?

Re: Alsa set default audio device

Check the "Alternative method" below on that same wiki page. You can set the default device via .asoundrc.

Getting the input from your usb webcam set as default input might be trickier though. I believe it could be done with more advanced .asoundrc tricks, but I can't really help with that.

Setting the default input in whatever applications you are using your mic with might be simpler solution, if possible.
