There CPU frequency is steady at 1540 MHz temperature is higher The only other OS that allows me to use gqrx on my OPI PC is XFCE Kali. Htop shows that pulse audio is using a rather big % of CPU On a text console running Armbian monitor -m shows lots of fall back to 480MHzĪlthough my well cooled CPU is around 30 degreesīut waiting more the sound gets bad again at times. Then you have to install pulse audio for an unknown reasonĪt start the sound on an FM station is very poor. No need to reboot and TV applications can use the dongle normally In spite of having the driver blacklisted it loads at start up but can be easily I'm trying to get gqrx-sdr to work with my RTL 2832 DVBT dongle. It takes a long time and then nothing works any more PS : The gqrx forum recommends to run volk_profile. To load back: the TV driver for the dongle : Then CPU use is much lower than in FM stereo One interesting feature is that you can select Demod Off In that case the sound gets bad and the launching console fills with zeros.īut it doesn't crash and stays reactive so you can correct parameters. I won't recommend using it without good cooling of the CPU. GQRX can be quite CPU intensive if you try for example to view 2MHz while You may have to use a mixer in case the volume is muted. Or the analog audio output it works nice. I could not manage to get a correct audio on the HDMI but with either an USB speaker This is because Armbian loads the TV driver but you just have to type as root Next problem is that if you want to use an RTL2832 dongle you get a message The pulseaudio one is as it appears that Debian uses that by default and it is not used in Armbian Starting it from a console there was a brief obscure allusion to pulseaudioĪnd a lot of messages :could not resolve property : pattern 10600 The problem when I first installed gqrx-sdr on my Armbian OPI PC is that it crashed Of course may be armbianmonitor is not the culprit at all In the below capture at 15:52:15 I stopped a CPU intensive task and instantly temperature fell by ![]() There is something strange with the temperature reading in armbianmonitor -m
