    Itĺs still loading the dwc_otg driver, you may need to remove the two entries from cmdline.txt.

    I removed "dwc_otg.fiq_fsm_mask = 0xF" and "dwc_otg.lpm_enable = 0" from cmdline.txt, but the result did not change.

    Since piCorePlayer could not recognize the USB-DAC, I am running it on Raspberry Pi OS Lite + Squeezelite.

    I just looked at our modules. We don't include the dwc2 driver. That would have to be manually added.

    sorry.
    I'm not very familiar with Linux so I don't know how to add it manually.

    P.S I'm not good at English because I'm Japanese.

    Unfortunately, piCoreplayer couldn't recognize the USB-DAC, but by using "DietPI", the CM4 can now use the USB-DAC.
    *USB-DAC iFi-Audio nano iDSD

    DietPI
    https://dietpi.com/

    * Write "DietPi_RPi-ARMv8-Buster.img" to CM4 eMMC or microSDHC.
    * Config.txt add "dtoverlay=dwc2,dr_mode=host"
    * Boot DietPi,Launcherinterface,select the DietPi-Software option.(Use ssh)
    * Select "Squeezelite".(Press the space bar)
    * Select "<ok>" install "Squeezelite"

    * use ssh

    sudo update-rc.d -f squeezelite remove

    sudo nano /etc/systemd/system/squeezelite.service
    ------------------------------------------------------------------------------------------------------------------------------------------------------------
    [Unit]
