Right, the audio device is connected by a USB 2.0 repeater cable (i.e.
1-port hub) to achieve a cable length of 10m.

Correct, the kernel config is new and untested.  ,)

I disabled the following:

uhci*   at pci? dev ? function ?        # Universal Host Controller (Intel)
usb*    at uhci?

...because the board uses a VIA chipset.

However, after reenabling these items the USB related messages look like:

I attached the audio device directly to the mainboard. The warning message
did not appear, but the problem with the playback persists.
