alsa underrun

Hi,
this problem of mine is giving me headaches.

wine application (Oblivion GOTY edition) doesn't work well with wine and alsa in Arch. I don't have this problem in other OSes.

wine version: 1.7.45-1
Kernel: 4.0.6-1-ARCH

Terminal output:

Wine cannot find the ncurses library (libncursesw.so.5).
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib32/alsa-lib/libasound_module_pcm_pulse.so
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib32/alsa-lib/libasound_module_pcm_pulse.so

ALSA lib pcm.c:7905:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:7905:(snd_pcm_recover) underrun occurred

The sound is distorted and the whole game is lagging so much that it's virtually unplayable.
When I disable the sound, however, the game is running without problems.

the library is in place

locate libasound_module_pcm_pulse.so
/usr/lib/alsa-lib/libasound_module_pcm_pulse.so
/usr/lib32/alsa-lib/libasound_module_pcm_pulse.so

Let me know how should I investigate further.

Thanks in advance for any help.

Why Linux? Because it doesn't hide anything from you. It puts you so closely in control of your machine that you can feel its heartbeat.

Re: alsa underrun

Don't use "locate" - it doesn't necessarily show what's on your filesystem *now*.

Better:

ls -l /usr/lib32/alsa-lib/

Re: alsa underrun

what does

pacman -Qs ncurses

After installing lib32-libpulse, the error with opening shared library disappeared, but underruns still occur.
I noticed that these errors sometimes occured in other applications, but never had any significant effect.

Re: alsa underrun

install lib32-libpulse

sudo pacman -S lib32-libpulse

edit: did not notice you mentioned installing it

pulseaudio --kill

Re: alsa underrun

pulseaudio --kill

pulseaudio --kill

doesn't help. It seems though that it stopped showing the underrun error, but I cannot be sure because the error doesn't show very often now. But the problems are still the same.

Re: alsa underrun

If it comes up again you can always try what this post suggests https://bbs.archlinux.org/viewtopic.php?id=185736

or run your program preceding it with

env PULSE_LATENCY_MSEC=30 wine....

Didn't help.
Also

I get a very very bad sound and many errors in the terminal (every 200ms)

, which is quote from the topic you linked, isn't my problem. I don't get a lot of these error messages (I did at first, but I guess installation of the additional packages solved this (mostly )). Sometimes there are none in the terminal, yet the problems still occur. I think it might have nothing to do with the underrun and those error messages are just a coincidence. But I might be wrong.

I guess my only clue right know is that the problems disappear when I disable sound in the game.

The distortion of the sound, however, does sound like an underrun. It wouldn't be so bad if it didn't lag the whole game.
Not all the sound cause this effect however. It typicaly happens when someone is talking, but not always and not exclusively. I gather it's not a good lead.

If you have some tips how to investigate further, I'd be glad to hear them. Thx for the help so far.
