Improved volume adjustment, and other minor software updates.
Hello Community!
We’ve just released the v1.41 firmware for your Tone2 Pro, you can download it from the link below:
Warning:
Do not power-off your Tone2 Pro during the upgrade process, doing so will permanently corrupt the device firmware
Please disconnect BT Magic before starting the upgrade process, failure to do so will result in corrupted MCU firmware
Do not use the Tone2's firmware with the Tone2 Pro's, doing so will permanently corrupt the Tone2 Pro's firmware
MCU Firmware Changelog:
Improved volume adjustment
Enabled HID volume support
Improved encoder operation experience with a new jitter elimination algorithm
Added support for BT Magic
Improved automatic input switching
Reduced probability of an unrecognized device
Solved noise issue when MQA files are played at max volume
XMOS Firmware Changelog:
Improved LED display indication
Fixed MFi version display issue
Fixed iMac wake-from-sleep issue
Fixed BT Magic's noise issue when playing back PCM768
Fixed Mac OS HID volume issue
Download XMOS Firmware:
Due to limited USB bandwidth, Tone2 Pro cannot support HID volume control and PCM768 at the same time, so these features were implemented separately in two firmware versions. Choose either the normal firmware or HID firmware for your Tone2 Pro's XMOS chip.
tone2pro-xmos-v1.41-221201 (supports PCM768, but not HID volume control)
tone2pro-xmos-hid-v1.41-221201 (supports HID volume control, but not PCM768)
Since the MCU firmware has been combined into the XMOS firmware, after upgrading the XMOS, it is necessary to replug (off then on) the power supply to enter the MCU upgrade mode, thus completing the entire upgrade process. During this time, the LED light will flash 3 times representing "Detect, Update, and Complete" respectively.
Known Issues:
When Tone2 Pro is connected, your PC will not enter the sleep state automatically.
(We have tried to solve this problem, but the current solution will cause an error exception when switching to the next DSD track, so we have not released this update)
The Tone2 Pro may become unrecognized when a Windows 10 PC wakes up from sleep. This issue was not observed on Windows 11 nor macOS.
How to Upgrade:
For v1.2 or later firmware, please check page 6 of the User Manual: Firmware Upgrade.
For v1.0 firmware (serial number starts with 0C… or 11…), in addition to updating the XMOS firmware, the MCU needs to be updated separately.
Required Software Tools: ASIO driver XMOS DFU tools MCU upgrade tool and firmware (only v1.0 firmware needs this)

Just Update to 1.41 HID. Volume control misbehaves. Trying to scroll up,,1/2 and going low instead , continus scrolling up 2-3 circles till get volume up. Volume control seems inaccurate.
Hello, I have Tone2 Pro 11 series....
Hello, I recently upgraded my tone 2 pro but now it stutters sometimes when playing flac files through vlc is this a bug from the software?
Hello, I have Tone2 Pro 11 series...., I did the update of XMOS via USB and MCU via ST-LINK, and now the led that indicates file type and bitrate does not work, as for the audio playback it works.
Why would I want the Tone 2 Pro to control the volume of my phone? If my phone is connected to the T2pro it’s either playing through headphones or my main speaker system.
okay. Sorry. Dumb question: Firmware 1.4 will update both MCU and XMOS with one click? Just have to unplug and replug?
Thanks
