Tagged: Rotary Encoder Volume control
15. März 2016 at 16:24 #19287
m using the Max2Play RaspberryPi 7"-Display Image on a RPi2 together with a cheap USB-Soundcard to emulate a Squeezebox Touch. Now Ive read that there exists a Plugin called „IQaudio“ that allows the configuration of rotary encoders to be used as hardware volume knobs.
My question is: does this plugin allow the use of a rotary encoder ONLY in connection with the IQaudio-soundcard or will it allow a rotary encoder to be used as volume control in ANY setup? Is there any option to change, let`s say the alsamixer that will be assigned to the rotary encoder action?
I would like to add a hardware volume knob to my „Sequeezebox“ without to much „fundamental research in linux“.
thanks for clarification! Flo16. März 2016 at 17:50 #19318
the rotary encoder in the IQAudIO image is only working with the IQAudIO cards as it directly connects to the card to set the ALSA Volume. We might build a more general way to change volume with a hardware control in future, but right now there is none. You might have a look at the IQAudIO rotary encoder code on Github to start your own project based on this code.

Thanks for your reply. I think i will stay with just a potentiometer before the amplifier in the meantime. Works, but is not that elegant. As soon as there is a simple option included in Max2Play to activate a rotary encoder I’m going to include one.
