Ist there any way to control the volume of an external amplifier? I am using the raspberry pi with HifiBerry DAC+ Pro. I connected a Wondom JAB3 (TPA250 DSP). I could for instance us an analogue input signal to control the volume of the Wondom amplifier. For that I need to have any chance to get the current volume out of one of the GPIO as an analogue signal.
Or are there any other implementations, maybe through I2C?
I searched around, but I could only find the way to control the volume of the raspberry through a rotary encoder or somthing like this. But this would only change the level of the signal coming out of the RSA (Chinch) of the HifiBerry DAC. I would rather like to change the volume directly at the amplifier.
Hi cyberthom,
Sorry about the late reply.
The Squeezelite players has an option for hardware volume control. Add hw:0 or hw:1 to your command line options, depending on the slot your sound card is in.
