Bugs and requests for KXStudio 14.04

[gazpacho]

I'd like to vote to keep sunvox within the next kxstudio even if it is no longer open source. The linux version on its webpage installs and works fine, so it would not affect us users removing it. But considering kxstudio a grouping of linux audio apps it would be incomplete if it did not include this amazing program actively developed with great new features on each new version. Thanks.

It seems that the Cadence ALSA bridge works OK under 14.04 if you install JACK2 but of course J1 is the default now.

Sunvox is easily the best free (as in beer) tracker, it runs on more platforms than any other similar app and its also small. As long as F continues to include Flash and non-free drivers/firmware he can't decline stuff on the grounds of it not being totally free. Maybe he should still include sunvox as I like it a lot too and there isn't a good FOSS alternative? I can understand why he'd want to drop REAPER as its not free, not native and depends on the wobbly world of wine.

My KX 14.04 install is much happier with J2 instead of J1. The ALSA bridge works properly, JACK starts more reliably and JACK2 correctly auto-detects all the IO ports on my Scarlett 2i4, which J1 fails to do. There are a couple of inputs (MIDI and something else, can't check now) on my 2i4 that JACK2 lists but I've been unable to activate under J1. Also, 'Switch Master' is no longer an option when using Cadence with J1 so in that case it'd be better if it could be greyed out.

I know F was claiming J1 supports Firewire better, but what were the other motives for switching to J1 as default again? Are you sure this was for best falk? It looks like a regression as far as my system is concerned.

+1. Jack2 works better on my 14.04. I don't use firewire, so cannot comment on that.

Another question to falkTX regarding wine. I read somewhere that besides the wine-rt patch, there are patches from Muse-research, which are supposed to improve wine realtime operation in a different way. As wine plays a pretty important role in my workflow right now, I'd like to ask if those patches had been incorporated into the main wine branch and/or into KXstudio or if there are plans to incorporate them. If no, if they compile against current wine and if they're generally worth to try.

pm-utils

You don't get a sleep / suspend option under KDE unless you have pm-utils installed so I'd like to see this included by default in the next KX iso please F.

There's a minor issue with Flash, JACK/ALSA and sleep mode - at least on my 14.04 install.

If you have a flash video open within Firefox when put your machine to sleep, it will be silent after resuming from sleep. If you open the same (or a different) flash video in a new tab or window, the sound works fine.

Not ideal but not a massive dealbreaker either. I'm sure many people can put up with that if its the only problem with sleep mode.

Looking into using the features of wine-rt patches, I discovered this script installed from the repositories:
/usr/bin/wine-rt

Apparently it should set the environment variables to load wine with the rt functionality initialized. Which is useful.
However it won't work with executables that have spaces in their path, unless this line:

Code: Select all

exec wine $@

gets a small fix:

Code: Select all

exec wine "$@"

Another wine-rt related request. For quite some time I'd been unable to run Altiverb in Reaper with WINE_ENABLE_PIPE_SYNC_FOR_APP enabled, getting "failed to create pipe object" errors in the console and then having wine crash and corrupt Altiverb storage data, and sometimes also corrupting Reaper config.
Looking at the patch, I saw that there's a comment saying "most likely reached fd limit" related to this message. So I googled this fd limit and tried to increase it. Apparently it's set in

Code: Select all

/etc/security/limits.conf

Increasing it to 8192 didn't help, so I tried 65536, and voila, no more crashes. I have only a vague idea of what exactly this does and what drawbacks might be, however apparently this is needed to run some demanding plugins under wine. So in case this is suitable for general use, perhaps it should be considered for KXstudio.

UPDATE: This has been fixed, thanx falkTX

Hopefully theres still room for another small KDE (Dolphin) tweak?

I think one of the most useful but largely unknown (because its quite well hidden) features of Dolphin is the space information indicator, which shows the used and free space of the drive you are currently viewing in Dolphin.

It can be enabled under Configure Dolphin -> General -> Status Bar -> Show space information but it'd be cool if KXS had it enabled by default.

[tangerine]

Yeah, took me some time to discover it, too

[RockHopper]

KX 14.04 seems to be missing the new Kubuntu Driver Manager which replaces Additional Drivers. Installing it will add a new entry in System Settings. I tried it out and it seems to work fine.

It can be enabled under Configure Dolphin -> General -> Status Bar -> Show space information but it'd be cool if KXS had it enabled by default.

You can also right click on the status bar which brings up a context menu allowing you to turn on/off the storage space info.

[RockHopper]

oh, I didn't notice this. What's the package name?

kubuntu-driver-manager

I'm trying out options on KXStudio and Linux Mint 32bit and have run into the following issue, not sure what's causing it:

When trying to install kxstudio-meta-audio-plugins-lv2 it produces a linuxsampler-lv2 related error, the other meta packages install fine

Many thanks, that's helped sort things out and it's working now.
