kencmh, I suspect that MPD from volumio does not support "dsd_native yes" option.

miero, I went with using WinSCP to /tmp and run the following command:

Code:
wget http://repo.ieero.com/botic/pool/mai...c3_1_armhf.deb

/tmp$ dpkg -i /tmp/linux-image-4.8.13-botic7-rc3_1_armhf.deb
Selecting previously unselected package linux-image-4.8.13-botic7-rc3.
(Reading database ... 33229 files and directories currently installed.)
Unpacking linux-image-4.8.13-botic7-rc3 (from .../linux-image-4.8.13-botic7-rc3_1_armhf.deb) ...
update-initramfs: Generating /boot/initrd.img-4.8.13-botic7-rc3

sync

reboot

/$ uname -a
Linux bbb 3.16.1-botic3 #1 PREEMPT Thu Aug 28 01:44:57 CEST 2014 armv7l GNU/Linux
That is, there was no update.

For me it is difficult to describe the sound in the English language. But bbb-botic-v3-2gb-w want to hear and hear, make louder, have fun. The volumio-2.041-2016-12-11-bbb, compared with bbb-botic-v3-2gb-w want to turn off. I beg you to excuse me, I speak bad English, I do not want to offend you. I'm trying to tell you about a technical problem.
I have two different images on different SD-cards. This makes it relatively quickly change the software. I did this a few times before you write. I listen through i2s. I have a galvanic isolation, a decent DAC, a tube amp and a speakers Dynaudio Contour 1.3 MK II.
For me, the sound is the same for the different version. You need to defrag your Linux file systems if you want to get better the sound quality. This is the only ways i know. The defragment level of bbb-botic-v3-2gb-w maybe better than volumio-2.041-2016-12-11-bbb.

My BBB with botic sounds great, but I have a problem with major drop outs lasting for several seconds. MPD sometimes looses connection as well, but not always. Probably something to do with the network, but I have no clue how to track down the error. Any suggestions to where I should look to find possible solutions to this? Any logs for example?

Take a look at the mpd logs - my guess if you are getting buffer under-runs. You could also tail the syslog and see if your network is dropping out.

Cheers!

Cyrilliu, I'm very sorry, but it is impossible what you are writing here ... your cable removal experiments has nothing to do with the audio device that is connected to the I2S/DSD output of the BBB. If there were a buffer inside S03, then the seeking operation would not work immediately, but it would be delayed by 50 seconds.

If that really happens, then you have another problem with your setup.

There is no magic in the BBB with Botic driver :-)

Thanks! I did look at the mpd.log (not sure if there is more than one?), but haven't looked at the syslog. Exactly the help I need, since I'm totally green on Linux ...

Btw: The mpd.log didn't report any errors.

So this was all in syslog, which doesn't tell me that anything is wrong? Strange date, though? I look into the logs to see if there is anything else ... Thanks again!
