I installed wampy on my A55. After insallation I see no change on the player. Everything is the same. What am I missing?

Have you tried toggling hold switch? Attach upgrade.log from internal storage
At what point do I toggle the hold switch? While installing? While booting? At some other time?

No, you toggle the switch to show the Wampy UI, so after installing it.
Sorry for needing the hand holding, but I did not find the installation or set up that intuitve. It works... well I found the settings anyway.

Added in v1.8.1
Wampy is unaware of BT, only standard music player is what counts.
Please check wampy/logs directory, there might be something. If there is anything, I need it.
================
Wampy v1.8.1
- upgrade volume tables plotting library (with out of bounds bug)
- stop fm radio if music starts playing
- fix digital clock build
- volume tables online editor at https://unknown321.github.io/wampy/
- updated documentation
I'd also like to thank everyone who donated; email notifications were off, so I noticed them only two hours ago.

Nice job!
The online editor wasn't loading the table for some reason - I checked in the console, and there's this:
These are all the errors:
I'm on Google Chrome, but it does this on Edge though (I know, they're basically the same).

Worked for me in Firefox. Fixed.

I thought about Firefox, but I don't have it installed.
It works now in Chrome too! Thanks a lot!

What exactly are “volume tables” and how did you uncover them? How do they differe from eq ?

I was going to send you a documentation link (as usual), but this is a good question, because I had no answer for it. I've updated the docs; here are the changes to save you some time:
Code:
What are volume tables for? They are used by CXD3778GF chip, which is also known as S-Master HX™ amplifier. Basically
they tell amplifier to amplify volume at X by value Y. Volume table application changes sound significantly, making it
at least louder, you can literally hear it while switching from `_cew` table to regular one.Can't say for sure, because I don't know how eq works exactly. Here is my simple take: volume tables amplify all frequences, while eq modifies only selected frequencies.
https://github.com/unknown321/wampy/blob/master/MAKING_OF_VOLUME_TABLES.md there you go, now it's time to read some docs.

So one additional question and if it’s documented I apologize… but given walkman one’s four tuning profiles (neutral, warm, bright, wm1z) if we boot up Walkman one on a50 on the wm1z tuning, would that be identical to booting up stock firmware and selecting wm1z on wampy? And if we select another devices volume table in wampy on Walkman one, does the “starting point” tuning of Walkman one have an effect in the volume table changes?

I think it would, but there is no confirmation. Tried to prove it by capturing audio from a50 on stock and w1 using REW via PC line in to compare it later, but it was a failed attempt - maybe I was doing something wrong, maybe linux sound system wasn't communicating with REW properly. I hope there will be someone with more sound measurement experience who can do it.
No, new volume table (wampy) overwrites old one (w1).

Are the values supposed to be a floating point-type (will it even work on the device)? On the device-Wampy there are only integers.
The floating-point type values show up when I zoom in at like the 13th mouse wheel click. The grid will start showing sub-divisions right at this point.
Edit: even if integers show up, you can place the dots to a value that's not an integer - if you zoom in, you'll see it, as well as you'll see the points having slight differences between them visually.

Fixed, now it rounds to nearest integer.Are the values supposed to be a floating point-type (will it even work on the device)? On the device-Wampy there are only integers.
