Inno-Maker AMP hat on B+

Postby N2QCN » Tue Jun 11 2019 00:33

My B+ with https://www.amazon.com/Inno-Maker-I2C-T ... B07CZZ95B9 is seen by the OS:
Code: Select all
[    9.565621] i2c /dev entries driver
[   10.255028] snd_bcm2835: module is from the staging directory, the quality is unknown, you have been warned.
[   10.256163] snd_bcm2835: unknown parameter 'index' ignored
[   10.257878] bcm2835_alsa bcm2835_alsa: card created with 8 channels
[   10.433564] snd-hifiberry-dac soc:sound: pcm5102a-hifi <-> 3f203000.i2s mapping ok
But setting Volumio's output to hifiberry DAC or AMP yields no sound. What should I try next?

Plugged the Inno-Maker AMP into a Pi B and it works!

Well, mute does not mute, but Hardware volume mixer works. Wonder what could be confusing the B+ ?

Never mind, it works just fine on a B+. Don't know what I did wrong the first time.
