Thank you for the FW update!
Over the last 3 weeks I've been connecting my M0 to an ifi nano black label dac/amp, and it's been working great. Two days ago the M0 player started disconnecting randomly with the text of "Audio Disconnected", and then it would immediately reconnect. After that happened a few times the M0 no longer connects at all to the nano. When I plug in the OTG cable the nano BL says it's connected, but the M0 never says "Audio Connected" and continues to play music out of the M0 headphone jack.
At this point I've tested and changed the OTG cable, updated the M0 firmware to the latest release, performed a factory settings reset in the settings menu, tried the reset button next to the SD card, and updated the nano BL firmware. The M0 still won't connect. Is there anything else I can do to troubleshoot this issue?
To add to the mystery, My M0 powers via USB without issue, and connects to a computer via USB without any issues. I also have a second M0 (my spouses) that connects to the nano immediately. so I can rule out the OTG cable as the root of the issue.

Could someone with a M0 please consider taking a look at these files? For some reason, the M0 is listing both in separate Michael Jackson entries...
Would really appreciate it!

I've added that PPA to my Linux Mint 19 repositories, and installed the updated Bluetooth packages - including the LDAC libraries (for transmitting, but not receiving).
When I paired up my M0 with my old Asus Eee PC 1215B Netbook, the M0 only showed up as a "Source".
So, my M0 could transmit music, as AAC, to my PC - but I couldn't stream any music to the M0.
Did some more Google searching, and then installed the blueman Bluetooth device manager.
Blueman allowed me to pair & connect the M0 as a "Sink" or a "Source".
I selected Sink, started Spotify on my PC, and the M0 shows it's connected as aptX - with the music playing on my earphones.
Success - mostly ... now I need to figure out what it takes to enable Linux Mint 19 on my Netbook for BT LDAC transmission to my M0 (and ES100).
After install this firmware there are bugs with spanish characters (see the song title and is happening on a lot of songs ) , please fix it for next update

Did this problem started out of nowhere or after firmware update?
Will check with our engineers for some advice.
Can confirm problem is added space in artist tag.

Will report this problem.
Spanish has only one unique character, the ñ, or also some others?
Line out setting has nothing to do with USB output. It only affects analog output.
I asked you on previous page if you can please give little bit more details. SO when you connect M0 to USB DAC, M0 volume has effect on the overall volume?

Wow, that's good news on Apt-X. Good luck with getting LDAC up and running.I've added that PPA to my Linux Mint 19 repositories, and installed the updated Bluetooth packages - including the LDAC libraries (for transmitting, but not receiving).

There is no such thing as "USB Line Out".
The term "Line Out" refers to an analogue signal of fixed volume, typically around 2 Volts RMS for peak signal.
The LO/PO switch therefore affects the headphone socket only and selects between a fixed 2V output (Line Out) suitable for sending to an amplifier or a variable output (Phones Out) suitable for driving headphones.
USB Out is digital and should be bit perfect and not attenuated by the volume control although I'm not sure if EQ affects the USB Out on the M0.
I'm having good luck with the v2.3 firmware. I've connected the M0 to a heap of different gadgets;
With my phone connected to it my car shows the streaming status correctly.
I also noticed that the tolerances on my M0 aren't great. I can see the light of the screen shine through the space inbetween the front panel and the aluminium body. There's about a mm of space between those two parts of the M0's housing.
- laptop (usb)
- desktop (usb)
- Xiaomi Mi Note 3 Android phone (usb & SBC bluetooth)
- my car (Rio GT 2018, bluetooth, doesn't show which protocol it uses, though)
- Mi Box 4K Android TV Box (LDAC)

Not only with the "ñ" character, happens with all the letters randomly.
Unfortunately yes; the problem (M0 won't connect to ifi Nano BL) started out of nowhere. I was just listening to music at my desk when it started losing connection, and ultimately refused to connect at all. My last firmware update was probably a month prior to the issue starting.
Thanks for the reply, and any help you can provide.

I've got it working!
My Asus Eee PC 1215B Netbook, running Linux Mint 19, is now streaming BT LDAC to my Shanling M0.
.
.
At the bottom of the page you linked to ( https://github.com/EHfive/pulseaudio-modules-bt ), there are a couple of manual steps, which add the LDAC modules to the Pulse Audio config file, after all of the automated installation steps that were done by the Synaptic Package Manager.
NOTE: I've un-commented the LDAC HQ line in my config file.
