RPi 3B Rev 1.2, pisound not found?

#1

I just got my PiSound and case, put them together and fired it up.

I have run the pisound-config script.

I have run apt-get update and apt-get upgrade multiple times.

aplay -l does not show it.

dmesg does not show anything on SPI.

I don’t know if there is a kernel module for this, but I haven’t found a *.ko file on my system. lsmod doesn’t show anything that I would correlate to PiSound.

I am running Raspbian on the RPi.

Hi, Pisound should be detected automatically and its kernel driver loaded.

Some common issues that can cause it not to be detected is insufficient power supply (we recommend using https://www.raspberrypi.org/products/raspberry-pi-universal-power-supply/#c-find-reseller, it’s 5.1V 2.5A), or the header pins may have to be slightly squeezed together to make better contact. You may first try to get it to work without using the 4 spacers.

Could you paste the output of this command:

uname -a

I had some problems with the latest Raspbian release so I went back to 2018-11-13-raspbian-stretch.img

pi@raspberrypi:~ $ uname -a

Linux raspberrypi 4.19.42-v7+ #1219 SMP Tue May 14 21:20:58 BST 2019 armv7l GNU/Linux

pi@raspberrypi:~ $

I have another RPi 3 that I will try out later today.

With regard to power supply, I am using a 15 watt 5v supply.

I took the case apart, took the spacers out, and voila.

pi@raspberrypi:~ $ aplay -l

What is the advice for making this work in the case? Only put spacers on one side?

Mount it with all 4 spacers, make sure the Pisound and Raspberry Pi boards are perfectly parallel, if they are not, gently squeeze the boards together on the header side.
