What is this? A rather easy fix, which combines the left and right audio channels into a mono channel. That way, you'll listen to both channels even on a mono speaker. (Keep in mind that you'll only have mono on both channels as well when using headphones!)
Step by step:
1. exit retropie (F4) or connect via SSH
2. type 'sudo nano /etc/asound.conf' (In my case this file was emty yet)
3. copy the code below into the file (all credit for the code goes to the poster from the link above)
Code: Select all
pcm.card0 {
type hw
card 0
}
ctl.card0 {
type hw
card 0
}
pcm.monocard {
slave.pcm card0
slave.channels 2
# type plug
type route
ttable {
# Copy both input channels to output channel 0 (Left) with half amplitude.
0.0 0.5
1.0 0.5
# Same for channel 1 (Right)
0.1 0.5
1.1 0.5
}
}
ctl.monocard {
type hw
card 0
}
pcm.!default monocard
5. type 'sudo reboot'
6. go to Retropie -> Audio -> Select your audio device (Jack or HDMI)
ORIGINAL POST:
Hi I'm kinda dissapointed by only hearing the left channel of my games...
So I'm looking for a way to add the left and right channels before they leave the Pi. What I thought of:
1. There is somehow a way of doing this globally for the Pis output....?
2. Find the piece of code in every single emulator and compile it myself. (Tedious af... but doable)
3. Adding the analog signals with a adding/mean circuit. I'm trying to avoid opening up my babies for the 1000th time.
Anyone has an idea on how this could be done?
Thanks, Fred
