This is most likely a problem caused by the HDMI audio chip on your video card. Notice that it is HW 0, so it is more likely to get assigned as "default" by some applications. Depending on what DE you use this is easy to see within System Settings. You can probably bypass all that and try, as root

Code:

 rmmod snd-had-codec-hdmi

That may be enough to remove the conflict but ultimately you will probably have to blacklist it to avoid doing that everytime you boot. You can run "aplay -l" again to see if HDMI has gone and only the one you're using remains. This all assumes of course that you're not using an HDMI cable off your video card for sound, but rather the common mini plug and jack off your sound card.

A lot of the HDMI sound chips are by Intel (and so is your "real" soundcard) so you may have to research this a bit to blacklist properly, but that is where the conflict seems to be.

Try switching VLC and MPlayer's audio driver to ALSA or OSS and add your user account to the audio group.

If ALSA still refuses to cooperate you may need to setup a specific /etc/modules.conf and an asoundrc file for ALSA as described here:

http://www.alsa-project.org/main/ind...dule-hda-intel

If that still doesn't work, you may want to try the Slackbuilds OSSv4 drivers.

open a terminal and type "id", look in groups, probally you're not member of group "audio" (number 17 for me)

do a "kdesu kuser" double click on you user and under groups tab, check audio, cdrom, plugdev (only the first one fix your problem, the second is for cdrecorder and the third is for mounting devices)

That damn kmix can be tricky, but if oss is the problem, check this post I had a while back that dugan answered for me. I have been using this method for sound in Slackware ever since.
