Modify the DAC type in the Settings page to RPI DAC, reboot, then reset your output type in the MPD page.
Go to the Settings page from the menu. In the section 'RuneOS kernel settings' modify the value of 'I²S kernel modules' from 'HiFiBerry DAC' to 'RPI DAC'.
Reboot via the menu 'Turn off' > 'Reboot'.
When the Pi restarts go to the MPD menu. In the section 'Audio output' modify the value of 'Audio output interface' to 'I-Sabre DAC (I2S)'.
That shoud do it.
The manufacturer of these DAC chips is ESS, all their I2S DAC’s have similar problems (chipsets ES9018, ES9028, ES9038). The company is very secretive and publishes no information about their DAC chips. There are drivers for Linux available, the one for the DAC’s which you mention is ‘i-sabre-k2m’ which is not published publicly. Manufacturers who do business with ESS do get the chip specifications and drivers, but further distribution is forbidden. For manufacturers of USB DAC’s this arrangement is not a problem, they solve all the issues within their products. For the I2S DAC users the ESS chipset it is a significant disadvantage. For these reasons I would personally not purchase an ESS based I2S DAC. Most other manufacturers use Texas Instruments chipsets (there are a couple of exceptions). The best-known suppliers include HiFiBerry, Allo and Just-Boom. For these, drivers and full chipset documentation is available.
Note: Audiophonics produces some excellent products, in this case it’s their supplier (ESS) creating the limitations.
