r3.8 requires a fresh install. I just noted in a recent message that this report saying an r3.7 installation has the latest update could be improved on. It's true in the sense that it has the latest update for the r3.7 series.

What model RPi? If an RPi3b, you can do boot directly from USB. If an RPi2b, there is an indirect method which bootstraps from a file on the uSD card to get to the USB drive. The RPi3B method has been discussed previously in this thread. Both it and the RPi2B method are discussed on the RaspberryPi.org site.

Kent
power cycling result in the same problem. Can the password be reset by booting the SD in another PC using "passwd" command but root or pi password does not work...

if I want to try r3.8 version, will I have to pay $10 so I can unzip the file?

thanks

This is most curious. Strong enough spurious radiation in the same frequency domain can interfere with WiFi communication. Microwave ovens and cordless phones are notorious examples of a spurious emitter. I'm not sure, though, how to relate your reported symptoms solely to such interference from the HiFiBerry product ([ed]: if it's an emitter, perhaps it's also susceptable to radiation from other devices?). It'll be interesting to hear if getting a new HiFiBerry DAC+ Pro also results in the issue going away---assuming you want to do the test by reconfiguring all your WiFi devices back to 2.4GHz

Hi Kent,

Residential power wiring is inherently noisy, and its subject to injected noise from light dimmers, appliances, etc., and it forms a giant copper antenna. Its definitely not the greatest medium for transmitting audio data.

Unlike bulk data transfers (Web, Email, Downloads, etc) which use TCP protocol (guaranteed delivery or fail), audio data transfers use UDP (best effort, no retries) and use isochronous transmission which requires that the network provides a guaranteed data rate for the duration of the transfer.

Noisy network + UDP + isochronous tranmission = audio glitches!

In an effort to solve this, I decided to try to take the USB connection to the DAC (Musical Fidelity V90) out of the chain. I installed a JustBoom Digi-HAT for the Pi3 to connect via optical (or coax) to the DAC, so the files play through that I2S device.

As they say... MISSION ACCOMPLISHED. No more pops/clicks, and audio high-resolution files are now playing in glorious 24/96.

So, if a MoOde user is using a USB connection to a DAC and is experiencing faint random pops and clicks, particularly with higher-resolution files, I strongly recommend a digital connection other than USB to the DAC instead.

Hope this helps someone!
Hi Dave,

Glad to hear this :-)

Did u try the USB (UAC2) work around on System config?

Hi Jean-Louis,

If I were to attempt to integrate it into moOde what would I need in order to test and verify that it works correctly?

Yes. That's why I asked whether files were being read via the Powerline Network or from local media when the issue went away.

On a totally unrelated subject, have you experimented yet with the BlueAlsa package in Raspbian Stretch? I got it up with just a couple lines of input. Right now I'm playing the soundtrack for the movie Pitch Perfect over a JBL Bluetooth speaker I happen to have. It's a lousy speaker but it suffices to prove BlueAlsa works.

Regards,
Kent

No.

However, if you have a Linux computer available (or possibly OS X, but I don't have it so can't comment) you can mount the second partition of the SD card and do some black magic to regenerate the password in the file /etc/shadow. See, for example, How are passwords stored in Linux (Understanding hashing with shadow utils).

If you have only a Windows computer available, you can always live-boot Linux from a USB drive. Google is your friend.

You should be able to reuse the key you used to unzip r3.7.

Hi Tim...

Yeah, I tried that work around, and a dozen other software and hardware attempts at fixing my faint "ticks" when playing high-resolution files over USB.

From my experience, digital out of the Pi is the best way to connect to a DAC. Thanks for your great software!

Hi Kent,

Stretch testing is just beginning for me. I'm still squashing the last few bugs in the Jessie build of moodeOS and moOde. Stretch brings new versions of ALSA, Samba etc and will take some time figure out.

Its nice to see that after the BlueZ project for some strange reason deleted ALSA support in Jessie is now supporting it again in Stretch.

Hi Kent,
thanks for your help. I now looked at the manual and nothing about consumption is mentioned. I looked USB up in wiki and 2.0 needs 5 V 0.5 A. USB 3.1 needs 5V and 0.9 A. So it could possibly work with the y-Adapter. If I try this device, I will post the results here.
Regards
Heiner

Hi Tim,

Can you add this to your list of features to consider for vNext:
Add links to the artist/album in the currently playing section in the playback tab?
They should jump to the browse/search box for the artist and the library/album for the album.
