Yep, basically same setup here. I'm using Kubuntu 20.04 and LDAC via pulseaudio-modules-bt. It'd be nice to have a fix for this.

@Shanling would you care to address my issue? Thank you, in advance.

Gave the new firmware a try, but unfortunately the volume limitation issue still exists. I can not achieve a loud enough volume when connecting my UP2 to my computer via USB Bluetooth dongle. This was not an issue with firmware v1.5. Please, do something to raise the maximum amplication/volume...

Yes, same here. Although the biggest difference was when using my UP2 with Kubuntu, the overall volume was also significantly lower everywhere else as well.

I had the same issue with 1.7.3, @chokini , but have thus far had no response or acknowledgment regarding it. In the meantime I had to revert back to the earlier firmware.

Just placed my order last night. Really looking forward to trying these!

@Shanling So any response about addressing the volume issue on the UP2 with V1.7.3?

Thank you for that, @brendancws .

Actually, that is the status of mine as well. Perhaps I used the term "in-transit" too liberally.

Saw that. I have a pair from Linsoul currently in-transit. That being said, aside from opening them no way to really tell which driver they have.

Maybe my experience better described is that my UP2 with firmware v1.5 demonstrates prodigious power and clarity. When using firmware v1.7.3, however, it feels a bit anemic. The most obvious difference being the volume issue.

Thank you for confirmation of a volume issue, although my problem was with LDAC, the only codec I've used with my UP2.

Yes, I am using a USB Bluetooth dongle on a Linux computer. The problem was both on the computer and on my Android phone. I was not able to achieve sufficient volume level on the computer and just a so so volume level on my phone.

Thank you for that! Kubuntu is my primary OS. Cheers!

Currently enjoying the Blon BL-03, but am looking forward to giving these a try once they arrive!

The Sedna Azla tips with a 2-3mm spacer at the base of the nozzle do the trick for me. I consistently get a good seal, prodigious amounts of base, and excellent overall sound.

Thank you for the firmware update! I'm using the UP2 and it has been great! That being said, although everything seems to work fine for me with the new firmware V1.7.3 the default volume level and/or the overall available volume range is too low. That is the case whether using high or low gain...
