Raspberry Pi 3: Temperature Spike When Using Sunvox
Posted: Tue Jul 04, 2017 3:57 am
Hi. (Firstly, thanks for this amazing software.)
I will try to give as much information as possible that may be relevant...
Running: RPI3, Raspbian Jessie OS, qjackctl, and a2jmidid, with sunvox raspberry pi version.
Other Hardware = Beringer uca222 usb audio interface, usb qwerty keyboard, usb midi controller (akai lpd-8), and official 7" touchscreen.
Background: with some excellent help from transient (noisyvagabond) before I had access to this forum, I dealt with a midi-to-audio latency issue I was having by running Jack, and using a2jmidid to connect the midi controller.
Problem: I start sunvox (from terminal), but even when running sunvox's basic default template, the core temperature appears to rise within a few minutes (about 5 minutes) to over 80 degrees Celsius! I noticed because a "thermometer" icon appeared in the top right. I confirmed this by running a command in a terminal which returned the CPU temp as 80.6 degrees Celsius. I stopped sunvox, and then ran the terminal command a few times over the next few minutes and saw the temperature drop through the 70s and 60s, until it levelled off at about 54 (then I turned off WiFi and it dropped a couple more degrees).
Further info: I never noticed this behaviour before I started using Jack and a2jmidid with sunvox (although in theory I guess the temperature could have risen to anything up to 79.9 degrees Celsius without displaying any warnings).
So:
1) Is there anything I can do to deal with this? (Heatsink already ordered but I imagine that this behaviour is unexpected and thought it best to report it, even if a heatsink makes it usable.)
2) Is there any further diagnostic test you would like me to run, or any further information that you would like me to provide?

Edited a sentence for clarity. (Edit 1)

I am using the 2.5A raspberry pi power supply, from RS components. I have not seen any "low voltage" symbol or any other error related to power. (Edit 2)
