Hakology Day 37 : Blog Entry

[1543]
Good afternoon hakologists, I’ve finally got the LED matrix ‘working’ I’ve managed to find one library that draws correctly to the screen, with a little bit of effort I think I could rewrite it for multiple matrices. Today I’m going to get a quick vblog together then later tonight hopefully record the SDR# video. Then we’ll take a look at multimon-ng and demodulating pager messages.

Need to send a massive shout out to gir, for sending hakology 2 RPi Zeros from the US as I couldnt get any at a reasonable price anywhere in the UK. Ridiculous considering they are made less than 50/60 miles from my house.

Family stuff over, vblog recorded, introduction video for vblog channel recorded, vblog rendering, time to get the kettle on and make a brew, thinking I might have a look at an old netgear router I have, see if I can connect using those new USB2UART boards. If I’m feeling really productive I might even get the sdr# video done.

Hakology – Retropie HDMI audio fix

No audio over HDMI on retropie? No problem, here’s your solution i’ve seen a few fixes on the web lots varied some were overly complicated so I decided to write up a really simple fix. Tested and working on the RPi3MB.

Boot retropie
Go to the retro pie menu
Go to the audio menu and press ‘A’
Ensure HDMI is selected, also check the mixer volume is at 100%
Save settings and return to the retropie menu
Quit emulation station
Run …
sudo nano /boot/config.txt

uncomment the following …
#hdmi_drive=2
so it looks like this …
hdmi_drive=2

also uncomment …
#hdmi_force_hotplug=1
so it looks like this …
hdmi_force_hotplug=1

Press ctrl+x to save the file.
now run …
amixer cset numid=3 2
and ..
sudo reboot

Hopefully you should now have audio over HDMI
