[SOLVED] Suptronics x400 device not working

[Tim Curtis]

moOde simply sets dtoverlay=iqaudio-dacplus for that particular device which is what the manufacturer specifies as the i2s driver to be used. There is no other configuration except to verify in MPD config that Audio device = I2S audio device, then click APPLY.

Here is config.txt for my Pi-ZeroW w/IQaudIO DACZero. This DAC works perfectly which confirms that their I2S driver is functioning properly.

Code:

pi@rp2:~ $ cat /boot/config.txt
disable_splash=1
hdmi_drive=2
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=off
dtoverlay=iqaudio-dacplus
#dtoverlay=pi3-disable-wifi
#dtoverlay=pi3-disable-bt

Maybe there has been some change in the dacplus i2s driver in latest Linux kernel ?? I would have no way of knowing...
