On the Pis that generate my UHF channels I use a single audio channel, and tell the pi to mix all audio down to mono.
I add the following /etc/asound.conf
My setup is slightly different because I'm using pi zeros, with the PWM routed to an audio filter on the GPIO, but I believe the alsa configuration side of things should be the same, or at least very similar.
I add the following /etc/asound.conf
Code:
pcm.card0 { type hw card 0}ctl.card0 { type hw card 0}pcm.monocard { slave.pcm card0 slave.channels 2 type route ttable { 0.0 0.5 1.0 0.5 0.1 0.5 1.1 0.5 }}ctl.monocard { type hw card 0}pcm.!default monocardStatistics: Posted by guesser — Thu Oct 17, 2024 11:47 pm
