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,

Hi, the rev 7 and rev 5 have identical /proc/cpuinfo here,.. if the rev 7 soc is advanced in any way than at least it is not documented in the cpuinfo, maybe that only same errors were ironed out ?, as it is the normal way with cpu's,.. and thanks for the info, so a change of values in Squeezeb

The 'EDO applet for the touch' (https://github.com/ralph-irving/EnhancedDigitalOutput) might be a good starting point for an applet to change the buffer period count and time for the radio. It doesn't allow you to enter values but rather supplies a list of options to choose from and the kernel u
