I have made a simple "Provocation" applet that automates my earlier
manual testing.
It will sound off a customized sound effect about every 1.5 seconds.
When I am playing a 48kHz sample rate stream on each of my two rev 5
radios, with default software and default jive_alsa settings, I find
that, after a few minutes, bass drop-out reliably occurs. It may take a
minute, it may take five minutes. But it does, reliably, happen.
Furthermore, if I let it all carry on running, the bass may
'spontaneously' be restored. Before dropping out again.
So I now have a slightly less tedious way of applying my earlier test,
and I offer it up in case anyone else wishes to duplicate it.
To install:
Get the attached zip file onto your Radio, probably using scp or
somesuch.
Log in to the Radio, and install the Applet:
Code:
--------------------
mkdir -p /etc/squeezeplay/userpath/applets/Provoker
unzip Provoker.zip -d /etc/squeezeplay/userpath/applets/Provoker
--------------------
Restart the radio, and look for the 'Provoke your radio' menu item on
the Home menu.
To remove, reverse the steps, with:
Code:
--------------------
rm -r /etc/squeezeplay/userpath/applets/Provoker
--------------------
and restart the radio.
The LMS 'Signal Generator' plugin is a good source of a 48kHz stream.
My next steps are to test with increased jive_alsa buffer sizes, test
with normal 44.1kHz streams, and make an applet to allow the jive_alsa
buffer sizes to be changed. I don't have a UE or rev 7 radio, so I don't
know how those would react to this test.
