           Summary: Unable to select audio format/sample rate/buffer size in
                    Traktor DJ Studio 2.6.2.117
           Product: Wine

            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

It is not possible to select the sample rate, audio latency and outputs in
Traktor DJ Studio 2.6.2.117 (demo version) available from

http://www.nativeinstruments.de/index.php?id=traktor2_us

If the ALSA driver is used the audio device "DS Intel ICH5" (or DS ICE1712 Multi
if I set my other card as the "default" ALSA device) is shown and selectable in
the Audio Device dropdown, but when the device is selected no entries will be
available under Sample Rate, Audio Latency, Master Left (Mono), Master Right,
Headphones Left (Mono) or Headphones Right. DS stands for DirectSound here.

If the OSS driver is used there are four "DS" devices under Audio Device but
selecting these won't do anything either.

With an earlier version of Wine (can't remember which one) this did work. The
dropdown did show both DirectSound and MME devices and I was able to select
sample rate, audio latency and outputs. Traktor did work quite well except that
the audio drivers did not support more than 2 channels so Headphone outputs were
not selectable.

I did some debugging on this both in the ALSA driver and on dsound and saw that
Traktor calls IDirectSound_IDirectSound_GetCaps which seems to return the
capabilities that the ALSA driver returned. I have no idea what Traktor is
looking for though in order to get things shown in the dropdowns.

This might be an easy one, I just don't know where to look. The fully usable
demo version of the program (in which this exists) is downloadable from the
Native Instruments site for free. The download is just 18 megs. You'll need the
Windows Media dlls but other than that it runs with a plain Wine installation.
