[SOLVED] unable to set I2S in Audio Output Device

[bikerman]

You did reboot the Pi after you selected the DT Overlay, right?



On a Pi 4B with the Innomaker DAC Pro HAT installed and moOde 9.0.4 booted, selecting either the allo-katana-dac-audio DT Overlay or the"Allo Katana DAC" Named I2S device, and rebooting, a Output Device "2:Allo Katana" shows up in the Audio config screen.

Whether or not I actually select that Output device, I get the following from the command line

Code:

rho@mpi4b:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 1: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 2: Katana [Allo Katana], device 0: fe203000.i2s-allo-katana-codec allo-katana-codec-0 [fe203000.i2s-allo-katana-codec allo-katana-codec-0]
 Subdevices: 1/1
 Subdevice #0: subdevice #0

If there's no "Katana" card showing up on your player then perhaps your suspicion is right. I'd double check to make sure the board is properly seated on the Pi's GPIO pins.

Yep rebooted.

A play doesn't show the card just the onboard HDMI and headphone.

Must be a DOA Hat

Thanks for all your help
