I'm running an HTC One m7 (AT&T) with MaximusHD 30.00.0 ROM(Android 4.4).
The good news is, I do have 30 ticks after setting, saving, and rebooting, but only on media. My phone volume ticks remained the same.
The bad news:
When I change volume, the standard 15 tick volumes still apply. What I mean by this is..
I start at muted. I click volume up once. Still muted. When I hit tick 3, I get sound. Tick 4, same as tick 3. Tick 5 will then increase volume, and tick 6 will remain at tick 5's level. Tick 7 increases, but tick 8 remains the same as 7.
Basically, It's only ACTUALLY changing the volume by one tick every two ticks that I input. The max volume is still the same loudness, as is minimum, I just have nothing in between.
I tested it with Beats Audio on and off, same results both ways.
I love the HTC One's speakers, but even the first tick of volume is too high to play my music only to myself in my office.
If I can provide any information, please let me know
I would absolutely love to get this mod running for my phone!
I'm tech savvy, but I'm far from a Dev. I am, however, always willing to learn, and welcome being corrected and taught new things!
