Added in
mha.algos = [transducers sine gain ]
mha.transducers.plugin_name = mhachain
mha.transducers.calib_in.peaklevel=[110]
mha.transducers.calib_out.peaklevel=[110]
It still works. Next need to get the Mic input working.

Re: using openmha with HiFiBerry DAC+DSP card
Adding the io.link=no allowed the cfg to prepare and start However then I started to add the required cfg to be able to generate a sine audio. mhalib = mhachain srate = 24000 fragsize = 55 iolib = MHAIOalsa nchannels_in=2 io.link=no io.in.device = null io.out.device = hw:0,0 io.priority = 90 mha.alg...

using openmha with HiFiBerry DAC+DSP card
I have openmha installed on a raspi with audio card HiFiBerry DAC+DSP. I am using Alsa and have ear pod connect to the audio card jacks, and apple airpods connected via bluetooth. Running the aplay commands: aplay -D hw:0,0 Front_Center_stereo.wav produces output to the ear pods connect to jacks apl...
