[Solved] Crackling sound in Wine

Question

Hi community,
I'm having some trouble with Wine's sound output. In all Wine applications (including winecfg) I get crackling sound and many of these lines:
ALSA lib pcm.c:7832:(snd_pcm_recover) underrun occurred
All non-Wine applications work fine. I know that the problem appeared some time ago, but since I didn't use Wine for a pretty long time, I cannot tell exactly when it appeared. Currently the latest version from multilib/ is installed (1.6rc3-1). Here is the list of opt deps (installed ones are marked as such):
Optional Deps : giflib [installed]
lib32-giflib
libpng [installed]
lib32-libpng [installed]
libldap [installed]

I need to say that I'm using the fix for crackling noise in Skype: https://wiki.archlinux.org/index.php/Sk … -bit_OS.29 (adding "tsched=0" to some line in /etc/pulse/default.pa). Trying to revert the fix left me without sound at all for some reason.
The .asoundrc (nothing changed as far as I remember):
$ cat ~/.asoundrc
pcm.dmixout {
# Just pass this on to the system dmix
type plug
slave {
pcm "dmix"
defaults.pcm.rate_converter "samplerate_best"
Thanks for any hint,
PhotonX

Answer 1

Thanks for your reply! I don't think, I use dmix, the .asoundrc is some default one (might actually be a pretty old one since I tend to carry my /home partition over to new system installs). I tried to remove it with no luck. pulseaudio-alsa has been already installed with following /etc/asound.conf:
# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
ctl.!default {
type pulse
fallback "sysdefault"
# vim:set ft=alsaconf:
Since nothing changed after removing .asoundrc, maybe this asound.conf has been used all the time rather than the .asoundrc?
Concerning the tsched=0 thing, the driver is snd_hda_intel (with snd_hda_codec_realtek), the card is an ALC887-VD. The Alsa page you mentioned states that indeed some cards with snd_intel_hda (seems to be the same as snd_hda_intel) driver have problems with timer-based scheduling, but doesn't specify which ones exactly.
So now I'm following your last hint and building wine-multimedia. It had lib32-libcl as make dependency which made conflicts with lib32-catalyst-utils, so I now try building wine-multimedia with lib32-libcl removed from the makedepends list, let's see whether it builds, it takes a while.  Will report back as soon as I have any news.
