Yes, dac volume is a known issue, I need to limit this in the driver according to a suggestion from HK. It’s on my list, I know what to do, just have not had the time yet because of other priorities.
Will be seen to soon, HK knows…

Nice! in the mean time it is always nice to learn more on DAC’s
I see the problem now. Maximum digital value for the hifi shield 2 DAC is 40, which is 0dB. You set it on detection to -7.5dB but the gui can change this too easy to 100 for example which is +24dB. You don’t want that coming out your RCA.
I set the maximum in the gui to 30 combined with natural. Startup value is 30 and only use it for occasional lowering of volume. Have to learn some more on alsa. I am using oss4 on my desktop, it’s a bit different. With oss4 (vmix enabled and disabled) master volume / gain is 0dB when set to 100 (or 255). Do not see a way to go above that.

The suggestion from hardkernel with a volume max (digital) set in the driver does not seem to have any effect.
I’ll get back to them.

New kernel was not integrated properly, so this is solved!!!
I will put it in the next version, the volume is now capped at 207 on the scale of 1-255.

For those who are interested:
http://updates.volumio.org/odroidc2/volumio/2.063/volumio-2.063-2017-02-06-odroidc2.img.zip
This is the new version with the volume issue resolved.

Nice, thanks!

Edit:
Did not work for me. Should I have cleared the data partition for this to work?
Gonna look at it tomorrow some more.

Edit:
Cleared data and did a fresh startup but no difference in max volume.

The 2.129 image is the first image where the Hifi Shield 2 works correct to me. (testet with a C2).
Thanks so much. The only thing is: after switch from HDMI to HifiShield 2 no 'restart’message comes but it is required!

Strange, i never do a restart. Will check it again though…

Can confirm the hifi shield 2 is working nicely with the latest official!
Only had a strange dhcp issue. My router is conmfigured to give the odroid a static ip of x.x.x.4 but the latest volumio gave itself a static ip of x.x.x.7. Changed the ip address manually in resolv.conf and now it’s back on x.x.x.4. Any idea where x.x.x.7 came from (router or volumio?) and how volumio gave itself a static address in contrast to automatic/request?

Hi,
not sure where this comes from. Anyway, there is a partial redesign of the wifi/ eth interface on its way.
If you have further issues then please feel free to open a new thread. I’m closing this one.
