Ian, I loaded up an IQAudio DAC+ onto a rpi4b (4gb).
It has pcp installed (running the default 32 bit kernel)
Code:
--------------------
piCorePlayer v6.0.0-b6 | linux 4.19.80-pcpCore_v7l | piCore v10.2pCP |
Squeezelite v1.9.6-1198-pCP
--------------------
I started playing "Stones in the Road".
I turned the pi on its long edge, with the audio outputs on the top.
The temperature bumped along at 51/52C.
At halfway through the album playback I returned it to the horizontal
position
The temperature averaged 55/56C
Added a gpio extender between the board and the dac.
I repeated the test with another album (Fat City).
The recorded temeratures were much the same.
Hope this is helpful
ronnie
