    Sound system headaches (kopete, new oss, alsa...)

    Hi. The story goes like this>
    to make sure KDE used ALSA, I selected it in the Sound system control 'panel' in "system settings". Over time, I learned about the OSS vs. ALSA thing - basically, I don't care if I supported "Linux-only", so I selected ALSA where possible, because the OSS emulation had some annoying issues with volume, when I, for example, seek in a movie or switched to/from fullscreen with mplayer or VLC.

    After some time, I grew tired of Vmware server not outputting sound whenever something else was playing because it could only use OSS (I tried the AOSS wrapper - I tried really hard - but it didn't work).

    Today, I finally got fed up with it and downloaded the new driver from http://www.opensound.com/ - installed it, rebooted, checked to see which sounds work, reselected OSS in amarok, kmplayer, smplayer, VLC and finally, in KDE's System Settings>Sound system. Now, I can even click "test sound" in the dialog and hear sound! Everywhere (VLC, KMPlayer, the sound works, more or less - I noticed that virtual machine probably has some limitations regarding sample rate (22050 doesn't play nicely).

    All in all, apps that have their own sound output settings, work. Test sound in System Setting> Sound System, works. Notifications in Kopete, Konsole bell - nada. Kmix is next to dead, trying to run it in Konsole yields:
    Code:
    $ kmix
    
    
    ********************  WARNING  *******************************
    Warning! kmix uses ALSA emulation instead of the native OSS API
    ****************************************************************
    
    kmix: relocation error: /usr/lib/libkdeinit_kmix.so: symbol snd_mixer_free, version ALSA_0.9 not defined in file libasound.so.2 with link time reference
    ERROR: Communication problem with kmix, it probably crashed.
    .

    Additionally, my keyboard behaves strangely - when I cycle windows with Alt+tab, I can no longer change the direction by holding/releasing shift.

    I should probably note that even before installing the driver, the sound system settings would only show in "system settings" - when I try to open the same dialog in KControl, it throws me back to it's info screen! Anyone else with this behaviour?

    Does anybody else here run the new OSS driver? What's your experience?

    half-SOLVED - somewhat... ALSA was, after installing the new OSS driver, emulated - there are however, some 'known issues' with OSS ALSA emulation, as can be seen here - I reinstalled:
    Code:
    libaudio2
    libartsc0
    libarts1c2
    arts
    What seems to have happened is that the symlink /usr/lib/libasound.so.2, which was linked to /usr/lib/oss/lib/libalsa.so.2.0.0 (OSS emulating ALSA) is now pointing to the original ALSA (/usr/lib/libasound.so.2.0.0) - not sure WHAT is used to play sound - alsa's modules don't seem to be loaded and after selecting ALSA in KControl's sound sytem, the test sound didn't play - so I take it that although present in the system, ALSA is not loading and whatever tries to access its library files is does so, but since the module isn't loaded, nothing happens. Basically, NOTHING requiring strictly ALSA should work now - not that I have something like that, although Adobe's flash plugin seems to do so. Opening the sound system control module in alone (NOT in systemsettings or kcontrol) actually works after reinstall and must have REALLY selected OSS for KDE's sound. I'll play with this some more tomorrow. Meanwhile, here's something I found on ubuntuforums:

    Btw, keyboard still sucks

      UPDATE:

      It seems that ALSA can't be easily uninstalled - and anything that needs original libasound suddenly doesn't work (SOME emulation that is... ). Even if I fix the symlink to point to original libasound, the OSS load script relinks it back to the emulation library upon reboot.

      Here I thought I'd start fixing the problem and lookie - no sound upon wakeup from S3 - that's it, the OSS driver brings in even more troubles than it solves... nice try, but mada mada dane.

      Some links for those who still want to try:
