Have you tried the patch I uploaded here back in May?

https://bugs.winehq.org/attachment.cgi?id=48661

I believe it vastly improves audio for PulseAudio users that are not
using USB devices. I'd be interested to know if it helps you.

I'm becoming convinced that the PA-ALSA plugin can't provide reliable
playback when USB devices are used. There was a discussion about this
back in October:

http://lists.freedesktop.org/archives/pulseaudio-
discuss/2014-October/022043.html

The ALSA API just doesn't provide a way to update client applications
that the buffer metrics have changed after the device was created. This
occurs for USB devices with PulseAudio. USB devices used to work in PA,
but their latency configuration was updated around PA 4 or 5, which
caused bugs for applications that can't handle high latencies, like many
Windows applications running in Wine:

https://bugs.freedesktop.org/show_bug.cgi?id=66962

I plan to send the above patch to improve winealsa. I had been hoping to
include a fix for USB-over-PA devices in the patch, which is why I
haven't sent it yet. As I showed above, I'm not convinced it's possible
to support this. The limiting factor is my time, I'm afraid. I need to
test the patch, over lots of test cases (a dozen applications on each of
non-USB, USB, PA non-USB, PA USB) and come to a decision on USB-over-
Pulse.

Title:
  Occasional sound drops in Wine via PulseAudio

  Fix Released

Bug description:
  Binary package hint: wine

  I'm running the Spotify Windows application on two laptops under Wine
  with both internal and external USB sound card. With both cards you
  get the occasional pop and click in the sound suggesting some data
  loss somewhere.

  I've selected the alsa drivers in winecfg and the whole thing is
  running via the alsa compatibility layer in pulseaudio.
