Re: No output on UDRC-II
Thanks for you response. I copied set-udrc-din6.sh to my-udrc-din6.sh, removed everything except the variables that you quoted, and I changed the levels to what you specified. Then I ran set-urdc-din6.sh to set all values to a known state, followed by my-udrc-din6.sh to set the values that you suggested (see below). Unfortunately, I'm still getting no output from the DIN-6 or the HD-15.
root@hammy:~# cat my-udrc-din6.sh
I redirected the script output to /dev/null for brevity; alsamixer confirmed the settings were accepted. I also tried setting force_turbo=1 in /boot/config.txt since it had been suggested here that the clock speed might affect the RPi 2. This appeared to make no difference.
Any other suggestions for troubleshooting this?
