Anyone else same experience or am I missing something?

Off topic and esoteric (apologies! ), but interesting because I've had similar experiences. For me, closing the *difference* between sound quality of redbook vs. higher-res sources came mostly from improving the quality of power to all components, but especially the DACs. But for playing through speakers, power quality has not been the only differentiating factor. I believe different driver designs and materials can permit more or less *intra-cone distortion that benefits from higher sampling rates*. Addressing that directly sounded like improving power quality to the various components upstream of the amps. After much tweaking, the downside of having such a high resolution system is that not so many recordings are recorded and mastered well enough to bring out the very best in the music. In my experience, the better the system, the more important is engineering of the recording and the less important is its sample rate.

How true. The dB/Loudness mess that too many mastering engineers have been into this past decade and longer is sad. Here is a web site with a list of albums and the recorded dynamic range.

Thank you !

yes, you are right! it seems that this does not work for volumio 2. i have tried that with all versions of the volumio2 and non of them worked. i got the message " can not open the output device" as soon as the botic split alsa is selected as output device. i reported that to michelangelo long time ago but no reply ;-) .... however, the botic split works perfectly with the boticized volumio 1.55 :-)

Could you or somebody else give me a link to download volumio 1.55?

Thank you !

EDIT: I am burning the SD card using Win32DiskImager - is this the wrong way for 1.5 version?

Hi Stefan!
It's a right way to use Win32DiskImager for any version of Volumio.
I think your issue with booting should be looked for in uEnv.txt file.

At May 2017 I see the latest image is 4.8.13-botic7-rc3_1

Q1. after installing the full botic-v4 image to MicroSD card,
then "ntpdate pool.ntp.org"
then "apt-get update"
can I update directly to 4.8.13-botic7-rc3_1 ?

Q2. do I update with "apt-get install" or download the deb first, and install with "dpkg -i"

Thanks.

OK, on a fresh botic-v4 installation I just used dpkg to install 4.8.13-botic7-rc3_1
as well as the corresponding 4.8.13 firmware.
Now when I boot up the 1st LED on the Hermes board fails to light, indicating that the output of the isolator is NOT enabled, so not external clock, and no output to Cronus.

Did you edit the /boot/uEnv.txt so that the line of dtb=am335x-boneblack-botic.dtb is included in it?

You might want to follow the instruction by miero. It was written for 4.5.0-botic7-rc1 but can be applicable to 4.8.13-botic7-rc3_1.

Regards,
