[SOLVED] No sound with IQaudIO Pi-DigiAMP+ (with Moode 9.2)

[tobitruba]

Audio Device: IQaudIO Pi-DigiAMP+
Issue Description:
After installing the new Moode Version 9 (9.2.0 and 9.2.1) (Raspberry Pi Imager and update), there is no sound output when trying to listen to "LR Channel and Phase" or any other audio.
When reverting to the previous version, Release 8.3.9 (32-bit Bullseye), the amplifier works flawlessly, and sound output is as expected.

RPI: PI Zero 2

Steps to Reproduce:

1. Install Moode Version 9 (9.2.0 or 9.2.1).
   
2. Configured I2S device
   
3. Attempt to play "LR Channel and Phase" or other audio.
   
4. Observe that no sound is produced.
   
5. Install Moode Version 8.3.9.
   
6. Configured I2S device
   
7. Attempt the same playback, and sound works correctly.
   

Troubleshooting Attempted:

• I attempted to copy the settings from version 8.3.9 to 9.2.0.
  
• On one occasion, this appeared to resolve the issue, and sound was available again on 9.2.0. However, I was unable to reproduce this result despite trying the process five times.

Run the command below and see if audio becomes unmuted.

Code:

sudo /var/www/util/sysutil.sh unmute-pi-digiampplus

[Tim Curtis]

Actually run the two commands below and see of that works

Code:

CHIP=$(gpiodetect | grep pinctrl | awk 'NR==1 {print}' | cut -d " " -f1)
sudo gpioset $CHIP 22=1

Thank you for the very quick solution!

The first command didn’t work, but the second approach did!

Not Working:
1.

Code:

moodeuser@moode:~ $ sudo /var/www/util/sysutil.sh unmute-pi-digiampplus  
gpioset: invalid offset<->value mapping: gpiochip0  

Working!
2.

Code:

CHIP=$(gpiodetect | grep pinctrl | awk 'NR==1 {print}' | cut -d " " -f1)  
sudo gpioset $CHIP 22=1  

After that, the sound was immediately back!

Thanks again, and I wish you a Happy New Year 2025!

Nice, I'll add that fix to the next release

If you want to try the fix run the command below. It will install the updated sysutil.sh file.

Code:

sudo wget -q https://raw.githubusercontent.com/moode-player/moode/develop/www/util/sysutil.sh -O /var/www/util/sysutil.sh
