1.4.1-Alpha-1 (High-End U1)

[agent_kith]

Thanks a lot, AK. 

I've just looked into grub, it's already set to new kernel.  After I run "update-grub", then it's fixed.  So I guess maybe it's about that command.

D'oh... You are right, either update-grub command isn't run or is commented out as I was testing. Have created a ticket to fix that.
 

BTW, the "shutdown" in webui is fine, yet the "reboot" button doesn't work.

Yeah, there's a typo in the reboot API, so this feature isn't working for both Pi and PC. Will be addressed soon.
 

Upgraded to 1.4.1 alpha-1. Sound stage has improved a lot. But, unable to play Mp3 files..

Will look into this, I already have the sample mp3 file but yet to test it. This is likely to come in 1.4.2 though unfortunately.
 

One discovery - the sample rate isn't showing in the music player "output devices" box. Tried the usual refreshes and whatnot and no luck. Not a biggy but I have found it useful to confirm when I'm playing around with upsampling on LMS via C-3PO.

Otherwise, it's playing beautifully so far this evening!

I commented out that bit of the code as that bit of code looked pretty terrible. Will clean that part of the code out and this will be working again in the next update.

All up I'm really glad this re-write is going well, I only have objective metrics to go on and while that is good, it's making me extremely happy that subjective metrics (the ones I value) are going great too.

There are only 2 or 3 downsides so far with the Qt migration:

1. The slight lag in displaying the console output when running programs (install, uninstall, updates, etc). There may be a way to speed that up, but other than that, it's worth the 1+ month effort on it. This update modified 413 files, with 32,463 lines added or removed. 
   
2. From what I can remember back when working on real time applications, i need to allocate all memories at program start. I am not following this principle in Snakeoil. So in theory the way I allocate memory may have some negative (or positive?) effects in audio playback. The idea is to have the option of adding a switch to do one or the other (i.e. pre-allocate everything vs dynamic allocation) and see what happens. That's the medium term goal of the API, and also to continue with the spirit of "designed by us, defined by you". Giving audiophiles the flexibility of - two ways of running API, plus not running the API at all (i.e. disable WebApp)
   
3. Qt documentation is really weird in a way. It tells you everything - but you have to read the manual and make sure you do not miss the important bits. E.g. Do not do database operations across threads using the same database object. Little things like that.
