my HW is raspberry pi 2, official 7'' display and hifiberry amp +
Just trying to install drivers.
I am using raspbian and version is 4.1.13-v7
I prefer using my own OS so I didn't use hifiberry image.
I did what was written in configuration linux 3.18 and high.
But many thing I diddn't do.
Step 1 - on my system is file /etc/modprobe.d/raspi-blacklist.conf empty with 0 bytes. It exists but is empty so there I didn't do any changes
Step 2 - there was no line like is in docu. I have there only 1 line with i2c-dev
So again I didn't do any changes
Step 3 -I did - I added the line dtoverlay=hifiberry-amp to config.txt
Step 4 - I created asound.conf like is in docu.
I connected loudspeaker, rebootted and no sound
when I look to
I can see that
card0 is bcm2835 ALSA
card1 sndrphifiberry [snd_rpi_hifiberry_amp]
What should I change?
