IP QOS on the Speedtouch 585v7

I've recently purchased a Pure Evoke Flow internet radio which appears to be an excellent dab/internet radio/audio streamer.

One thing I'd like to do is to ensure it's streaming traffic is prioritized. Whilst there is some buffering it would be good to ensure that mass downloads don't start causing audio breakup/delays when listening to radio.

I therefore took a look at the Speedtouch IP qos guide and made the following changes in the CLI:

:label add name=AudioStream
:label modify name=AudioStream classification=overwrite defclas
s=11 ackclass=11 bidirectional=enabled inheritance=disabled tosmarking=disabled


* Mark all packets destined to the radio
:label rule add chain=qos_user_labels index=1 name=AudioStream dstip=192.168.1.74 log=disabled state=enabled label=AudioStream

I hoped this would work, but when I use "ipqos queue stats" all packets are going into class 2... I'm not yet clear how the 6 queues there map to my label definition above ie:

So if anyone can clarify this please let me know. The information isn't widely discussed on the web.
