[Bug 19908] New: wine jack audio out is mono

http://bugs.winehq.org/show_bug.cgi?id=19908

Summary: wine jack audio out is mono
           Product: Wine
           Version: 1.0.0
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

configuring wine to use jack then run a win32 application the following
Readable client is created in jack.

wine_jack_out_0

within this there re two ports: out_l and out_r - which woujld presumable be
the stereo channels.

when running an audio source programme in wine audio is outputted from both
these ports however both have the same signal and the audio is not the original
stereo audio. I think it is just one channel split onto both out_l and out_r
rather than a summed mix.
> From audio.c this appears to be the behaviour if the audio source is considered

mono - the data is copied to both channels.

The win32 audio source application has been verified to operate with wine in
stereo using the alsa output.

Is there anyway of making wine output the missing stereo data? Should
wine_jack_out_1 carry the lost second channel? If so how do you get wine to
create output on wine_jack_out_1 too?

Upgrade Wine, latest version is wine-1.1.28.
What program are you using to test this with? How do you know what exactly is
it outputting?

Hi

I've tested this with a few programs including vlc for win32 for windows and
all give mono output. The application I specifically need it for is a
proprietry win32 application. All these applications output stereo when wine is
configured for alsa.

So I'm pretty sure this is wine-jack specific for a range of win32
applications.

I verified that the signal is mono my loading the recorded data using audacity.
I have spent some time making sure there were no other possibilities for the
mono problem with different setups (it involved streaming from either alsa or
jack sources using liquidsoap or darkices to decouple any connection problems)
when switching between alsa and jack connections from wine the signal switched
from stereo to mono.

Is there a specific fix for a mono problem in 1.1.28?

I just tested with wine-1.1.28 and found the same problem.

I would have thought this was more than minor? wine and jack would be a very
useful application of wine for serious audio system integration projects if
such features were implemented completely.

I suspect the fix for this would not be difficult.

Not critical.

AFAIK, no one is actively working on this.

I'm running wine-1.1.30 on a Gentoo box, and I can confirn this bug.

Since I (and maybe some other people) use Wine to run Spotify, I cannot agree
that this bug is considered just minor. Does anybody have a workaround?

I found that if jack is configured with the same sample rate as the application
(e.g. no resampling from 44.1KHz to 48Khz necessary) then this problem can be
worked around.

Indeed it does work when configured as you suggested. Thanks for the
workaround. :-)

With this work-a-round there still appears to be a low level distortion effect
if you are considering using this for high quality audio applications.

Wine no longer supports JACK audio.
