The wm8960 is already supported by the mainstream kernel and a DTBO is already included in the "/boot/overlays" directory. Please, could you try to load this DTBO? It would simplify things with zynthian ...
Hi @jofemodo thanks for considering this. I am happy to test things out but need a little guidance.
Please, could you try to load this DTBO? It would simplify things with zynthian ...
Is the below approximately what I should do?
grep -q "dtoverlay=wm8960-soundcard" /boot/config.txt || \
echo "dtoverlay=wm8960-soundcard" >> /boot/config.txt
Do I need to also do more, like the following?
#set kernel moduels
grep -q "i2c-dev" /etc/modules || \
echo "i2c-dev" >> /etc/modules
grep -q "snd-soc-wm8960" /etc/modules || \
echo "snd-soc-wm8960" >> /etc/modules
grep -q "snd-soc-wm8960-soundcard" /etc/modules || \
echo "snd-soc-wm8960-soundcard" >> /etc/modules
#set dtoverlays
sed -i -e 's:#dtparam=i2c_arm=on:dtparam=i2c_arm=on:g' /boot/config.txt || true
grep -q "dtoverlay=i2s-mmap" /boot/config.txt || \
echo "dtoverlay=i2s-mmap" >> /boot/config.txt
grep -q "dtparam=i2s=on" /boot/config.txt || \
echo "dtparam=i2s=on" >> /boot/config.txt
#grep -q "dtoverlay=wm8960-soundcard" /boot/config.txt || \
# echo "dtoverlay=wm8960-soundcard" >> /boot/config.txt
Would I also need https://github.com/waveshare/WM8960-Audio-HAT/blob/master/wm8960-soundcard, https://github.com/waveshare/WM8960-Audio-HAT/blob/master/asound.conf, and possibly more?
What is unclear to me is how what I am doing on the command line interacts with the Zynthian GUI, and whether there might be conflicts.
The first modification to /boot/config.txt should be enough. At less it's enough with most soundcards. You should try it and see if it works ;-)
Thanks!
If I add dtoverlay=wm8960-soundcard
to /boot/config.txt
and reboot (still with the C-Media USB Headphone Set attached because without it will not boot up all the way into the GUI, showing instead the frightening Zythian logo shows up - disappears - Zythian logo shows up - disappears - Zythian logo shows up - disappears loop), then I do see the new device via ssh:
root@zynthian:~# cat /proc/asound/cards
0 [fmidi ]: MIDI Gadget - f_midi
MIDI Gadget
1 [b1 ]: bcm2835_hdmi - bcm2835 HDMI 1
bcm2835 HDMI 1
2 [Headphones ]: bcm2835_headpho - bcm2835 Headphones
bcm2835 Headphones
3 [Set ]: USB-Audio - C-Media USB Headphone Set
C-Media USB Headphone Set at usb-0000:01:00.0-1.4.3, full speed
4 [wm8960soundcard]: wm8960-soundcar - wm8960-soundcard
wm8960-soundcard
How do I use it now? Trying
Rebooting.
Now I get the frightening Zythian logo shows up - disappears - Zythian logo shows up - disappears - Zythian logo shows up - disappears loop.
What do I have to enter into the "Jackd options" input field? It would be nice if this field would be automatically populated correctly based on the hardware autodetected in the device.
Also, after the reboot it seems like the device as disappeared?!
root@zynthian:~# cat /proc/asound/cards

3 [Set ]: USB-Audio - C-Media USB Headphone Set
C-Media USB Headphone Set at usb-0000:01:00.0-1.4.3, full speed
and indeed, /boot/config.txt
no longer contains my change...
Retrying with:
and rebooting.
Geting the frightening Zythian logo shows up - disappears - Zythian logo shows up - disappears - Zythian logo shows up - disappears loop again.
Now I cannot uncheck "Disable RBPi Audio" anymore. As soon as I uncheck it, it gets checked again immediately. /boot/config.txt
now contains:
# Enable RBPi Onboard Audio (Headphones)
#RBPI_AUDIO_CONFIG#
# Soundcard Config
dtoverlay=wm8960-soundcard
And for whatever reason, wm8960soundcard
is no longer in /proc/asound/cards

Did I break my system beyond repair?
