KDE can't find OSS devices

[ColdfireMC]

Hi

I have installed FreeBSD 9 with a KDE4 desktop but I can't get any sound from KDE interface (like start sound, buttons and anything that use phonon) but some other programs run with complete sound support (i.e, Opera, flash player plugin, VLC, XMMS, MAME146, any SDL based program). this is ossinfo output

Version info: OSS 4.2 (b 2005/201112060457) (0x00040100) BSD

Number of audio devices:        4

Nodes
  /dev/dsp -> /dev/oss/oss_audigyls0/pcm0
  /dev/dsp_in -> /dev/oss/oss_audigyls0/pcm0
  /dev/dsp_out -> /dev/oss/oss_audigyls0/pcm0
  /dev/dsp_ac3 -> /dev/oss/oss_audigyls0/pcm0
  /dev/dsp_mmap -> /dev/oss/oss_audigyls0/pcm0
  /dev/dsp_multich -> /dev/oss/oss_audigyls0/pcm3

It seems to be right... but phonon only list a sound device called "default" and that device it's no emitting any sound :\

How I can set phonon to use my OSS device?

Did you ever find a solution to this? I have this same problem with FreeBSD 10.3. As long as a program uses /dev/dsp, it's fine (e.g. I can play video files with sound just fine in mpv or vlc), but if it's KDE-specific and hooks into phonon (like amarok), then there is no sound. Unfortunately, I'm forced to use OSS, because the kernel driver for my sound card is quite poor. So, I'm stuck with OSS, and as far as I can tell, that means that phonon is screwed. But it seems like there _should_ be a solution to this.
