JACK Audio in Wine 1.4

[falkTX]

Hey there everyone!

Wine 1.4 has been released and in the new version JACK Audio support has been dropped
(This is not related to WineASIO, that still works as usual).

Upgrade to this version is recommended, but what to do about JACK Audio, say in Games and general applications that don't use WineASIO?
The answer is here -> http://wiki.winehq.org/Sound (Check "Using snd-aloop with JACK")

I've been using it myself for ~2 months now and it works great on Ubuntu 12.04.
I need to manually run 'sudo modprobe snd-aloop' first, but even that can be scripted.

If you're running Wine 1.4, please give it a test.
This is the implementation I'll be using for all ALSA sound in KXStudio for 12.04.


PS: If you're wondering... yes, I made that asoundrc and python script.
Thanks to JackWinter for his initial asoundrc config!

Hi,

This doesn't affect Ardour with WinVST I assume since it doesn't use JACK set up in the Wine config either so the amount of apps really affected should be quite small. falktx do you have an -rt patch for 1.4 or does it utilize the same patch used in 1.3.24 ?

afaik, the patch remains the same, and should still be compatible.
I'm waiting for Ubuntu 12.04 to get the final Wine1.4, then I'll try it.

And you're right about ArdourVST. This asoundrc+script "trick" is only for the native Windows apps, not Wine-mixed ones (like ArdourVST, fst/festige, dssi-vst, lmms-vst, etc).
It's useful for at least games and media players.

Thanks for reporting, I'll speak to the Wine devs and ask why they did this.

thanks, I saved the html now.
Did you create the "code"?
If so, could you point out the diference to this: http://alsa.opensrc.org/Jack_and_Loopba ... ack_bridge ??

Yes I did that code myself.

Main differences:
- my script gets the currently running jack buffer-size and sample-rate. you don't need to set them manually.
- auto-adapts to buffer-size changes on the fly
- the script and alsa_in/out are stopped when jack stops

falkTX, tried your python script, but I got a syntax error:

Code: Select all

[studio@myhost ~]$ ./.loopback
  File "./.loopback", line 92
    jacklib.jack_set_buffer_size_callback.argtypes =
                                                    ^
SyntaxError: invalid syntax

Try to run the script with a different python version. Although it works with py2 and 3 on my system, python3 might have more changes that I don't know of yet.
I think 'python2' will work there (edit the file, 1st line)

tried that, didn't resolve

try to force by running it manually, like:

Code: Select all

python ./.loopback
python2 ./.loopback
python3 ./.loopback


If it still doesn't work, you probably didn't copied the file properly or in it's entirety.

ok, I found the problem. I had copied the code 3 times tom make sure, but now I had a look at it and found out that my terminal program broke the line in the code causing the problem. I had to copy the code with a maximised terminal window to solve this.
Now it runs, only manually though
thanks
