USB Sound Card & default device?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi all,

I just got a new USB sound card (Schiit Fulla 3, https://www.schiit.com/products/fulla-1). It works great, and I'm using it to play music through CMUS (https://cmus.github.io) on Arch Linux.
However, I can't seem to figure out how to tell ALSA which device to use as a default. When the Fulla 3 is not plugged in, I get:

# cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xa1110000 irq 129

This is just the internal sound card of my laptop. After I plug in the Fulla 3 on the USB port, I get:

# cat /proc/asound/cards

So far so good. In CMUS, the default settings for the ALSA plugin are:
setting: 'dsp.alsa.device=default'
setting: 'mixer.alsa.channel=PCM'
setting: 'mixer.alsa.device=default'

With these settings, sound gets played on the internal sound card.
My problem is that I can't seem to figure out how to direct sound to the Fulla 3 instead of the internal sound card. So far, the only workable option that I could figure out is to change the module loading order (https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#Set_the_default_sound_card). When I add /etc/modprobe.d/alsa-base.conf:

# cat /etc/modprobe.d/alsa-base.conf
options snd_usb_audio index=0
options snd_hda_intel index=1

then the order of the cards is reversed, and CMUS will output sound to the Fulla 3 rather than to the internal sound card. This method works, but is inconvenient, because switching from one card to the other requires me to edit /etc/modprobe.d/alsa-base.conf and reboot. I'd prefer to just change the ALSA plugin settings inside CMUS, independent of the order of the sound cards. 
Can anyone tell me how to configure CMUS to use the Fulla 3 or the internal sound card, no matter how ALSA sorts the cards? The Fulla 3 has a volume control dial, so I actually wouldn't need volume control from the computer (I guess that's the 'mixer').
Greetings, and thanks a lot,

Hans
