I get static noise on the analog audio out when no sound is playing (I use alsa). I tried to add a configuration file in /etc/modprobe.d which disables power saving (as this appears to be the usual reason for static noise), but this does not work. Does anyone know how to resolve this?

I noticed that in idle Arch draws almost 2 Watts more than amrbian. Maybe I need to experiment with the cpu governor and min and max cpu frequency settings.

I did select the HC1 optimization in armbian-config. On arch uname gives me 4.14.165-1-ARCH.

Update. So I tried on ArchLinux. There I get roughly 370MB/s.

Thanks for post. uname gives me 5.4.28-odroidxu4. I don't have another SSD, but I doubt the problem relies with the SSD as it is (essentially) brand new.

I run armbian on an Odroid HC2. Using hdparm -t /dev/sda I get merely roughly 130MB/s on buffered disk reads. This is way below the expected value for my 2TB Crucial SSD. It is obviously not a major issue as the speed is anyway bottlenecked by the gigabit ethernet. I'm just curious, does anyone get better speeds with a similar setup? I read that poor performance can result from a misaligned partition. Checking the alignment with "align-check" of parted does report that the parition alignment is fine, so I suspect this is not the issue in my case.

Many thanks! That's very helpful. And to answer the question above, yes, I tried conservative as governor as well. It was also not really usable.

I run Armbian 20.02.1 stable on a zeropi which is used as a wireguard server and spotify direct client (USB to external DAC). Things run very well. Many thanks to everyone involved in keeping Armbian such a great distro! I noticed that when I turn on the ondemand governor the system becomes very unresponsive and music playback is stuttering. When I use the performance governor (even with min and max frequency both set to 480MHz) things run just fine. Most of the time 480MHz will be sufficient, but it would be nice to be able to take advantage of the ondemand governor. Any help is greatly appreciated.
