Respeaker2 stopped working after upgrading

hugocoolens · April 24, 2021, 8:18pm

I finally upgraded to rhasspy 2.5.10 (using docker-compose down, docker-compose pull
docker-compose up -d) I also upgraded raspberry os. Unfortunately my respeaker2 doesn’t work any longer with rhasspy. This is what I get when using the command line:

pi@rhasspy1:~ $ aplay test.wav
ALSA lib pcm_direct.c:1824:(_snd_pcm_direct_get_slave_ipc_offset) Invalid value for card
aplay: main:828: audio open error: No such device
pi@rhasspy1:~ $ arecord -L
null
Discard all samples (playback) or generate zero samples (capture)
jack
JACK Audio Connection Kit
pulse
PulseAudio Sound Server
default
playback
capture
dmixed
array

Can anyone here help me solving this issue?

kind regards,
hugo

Try Hintak’s fork of the respeaker driver:

follow those guidelines to downgrade the kernel until HinTak updates the code to the current kernel version

github.com

HinTak/RaspberryPi-Dev/blob/master/Downgrading-Pi-Kernel.md

## Raspbian

For the purpose of downgrading from 5.10.17 (`raspberrypi-kernel_1.20210303-1`) back to the last of 5.4 kernel (`raspberrypi-kernel_1.20210108-1`), to
investigate driver breakage, I did:

```
wget -O kernel-headers_armhf.deb http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/raspberrypi-kernel-headers_1.20210108-1_armhf.deb
wget -O kernel_armhf.deb http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/raspberrypi-kernel_1.20210108-1_armhf.deb
sudo dpkg -i kernel-headers_armhf.deb kernel_armhf.deb
sudo apt-mark hold raspberrypi-kernel-headers raspberrypi-kernel
sudo apt-mark showhold 
```

The last step (`sudo apt-mark showhold`) is for verification. The `sudo apt-mark hold` step stops them from getting auto-upgraded.

To unhold (again, repeating the first step of verifying current holds), and go back to the latest:

```
sudo apt-mark showhold 
sudo apt-mark unhold raspberrypi-kernel-headers raspberrypi-kernel

I reinstalled the driver using:
./install.sh --compat-kernel

that fixed the problem

thanks

HinTak should actually work on the current kernel, the branch may be named v5.9 but it works for 5.10 also.

Thanks for the reply, but I already followed Koan’s procedure and that works well

kind regards,
