Ok, in this case, it supports both - QC on the USB-A-Port and USB-PD on
the USB-C-Ports.

Many Chinese phones like Xiaomi or Huawei use QC and not PD.

As I already suggested: most likely the Bluetooth speaker you mentioned
does not support USB-PD at all since this is not that relevant on the
Chinese market (yet). It will just take what it gets and the USB-C input
is just for convencience, so it is easier to use a cable provided with
your QC compatible phone and the QC charger which usually uses a USB-A
connector for the carger side.
