Tone2 Firmware request: Disable startup volume fade

Hi Khadas Team,

I’m using the Tone2 Maker Kit for a custom car audio build. The board is installed in the trunk and connects straight into my DSP. Since it sits completely hidden away, I control all my music volume directly on my phone, meaning the Khadas internal volume always needs to be at 100%.

Every time the car starts, the firmware takes about 8 seconds to slowly fade the volume all the way up to 100%.

In a car setup, my amplifiers and DSP turn on in 1–2 seconds, and my phone connects to BT Magic in ~4 seconds. When the music autoplays, the audio spends the next 4 seconds awkwardly ramping up from 50% to full blast.

I don’t have the compiler environment set up to build the firmware myself. Could someone please provide a pre-compiled firmware file that just forces the internal volume straight to 100% (step 32) instantly on boot without any fading or delay, or maybe just fade it much faster (in 1–2 seconds) to the last saved volume?

Thanks!

Check if it can be set on the mobile music APP
