How do I change the default sound card? - zirconx - 10-01-2016
I would like to change the default audio to the headphone jack. I am running dietPi (no gui/de). I know I can change the alsa default card with an environment variable or asound.conf, but I think that only affects alsa utilities. I'm also using sox, so I just want to change the default (first) card at the OS level. Actually I could settle for getting sox to pick up a different card by default but I have not been successful in that.
So I think I need to create a file in /etc/modprobe.d, with lines like
Quote:options sunxi_sndcodec index=0
options sunxi_codec index=1
I also tried reversing them:
Quote:options sunxi_codec index=0
options sunxi_sndcodec index=1
but it's not working. The hdmi output is always listed as the first card.
Code:
root@DietPi:~# cat /proc/asound/cards
0 [sndhdmi ]: sndhdmi - sndhdmi
sndhdmi
1 [audiocodec ]: audiocodec - audiocodec
audiocodecI'm just guessing at the driver names based on lsmod. Any ideas? Thanks.
here's the output of lsmod.

Ok, so the ALSA asound.conf change I've mentioned somewhere (do you think I can find it again?
) probably won't help... SOX doesn't uses ALSA? Anyway, maybe have a look at /etc/modules-load.d/pine64-audiojack.conf ... maybe move sunxi_sndcodec up to to the top and see if that makes any difference (fingers cross no nasty errors ensue!)... I'd try myself but my bed calls...
