example of alsa-base.conf needed

[Hugo Coolens]

Dear all,

I installed the image in matthew_curry-jasper-img-992d80589279.zip on an SD-card, booted my rpi3b, ran ./jasper-repo-installer.sh and edited profile.yml. When I run  ./jasper-client/client/main.py --local, jasper answers some questions, which is great.

Unfortunately the sound isn't configured correctly on the system. When I try to execute "arecord temp.wav" I get the following error:

arecord: main:788: audio open error: No such file or directory

I think this is due to the fact that /etc/modprobe.d/alsa-base.conf is missing, I tried to make one myself like this but it doesn't work:

options snd_usb_audio index=0

options snd_bcm2835 index=1

install sound-slot-0 /sbin/modprobe snd_usb_audio

install sound-slot-1 /sbin/modprobe snd_bcm2835

Could anyone here help me further with configuring the sound correctly or provide me a working set of of the files:

/etc/modprobe.d/alsa-base.conf

and

/usr/share/alsa/alsa.conf

thanks in advance

Hugo

I found the solution:

I had to create the file /etc/modprobe.d/alsa-base.conf

with the following content:

# Load USB audio before the internal soundcard

options snd_usb_audio index=0
options snd_bcm2835 index=1

# Make sure the sound cards are ordered the correct way in ALSA
options snd slots=snd_usb_audio,snd_bcm2835

testing worked as follows:

arecord temp.wav

aplay -D hw:1,0 temp.wav
