I have the same problems with my HDA NVIDIA AD198x:

**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: AD198x Analog [AD198x Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: AD198x Digital [AD198x Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

KNotify tells me, that my HDA NVIDIA AD198x Analog doesn't work and switches to HDA NVIDIA AD198x Digital.

It only occures at system-startup, not always but very often (~50%).
Sometimes I'm getting the KNotify-message two times (with a delay of about 5) seconds).
I noticed that after a restart of Amarok, the device is working again, so maybe something is locking the device ? However, it also occures, if Amarok is not started.

I'm using KDE 4.2.4 with Phonon 4.3.1 (Xine) on openSUSE 11.1.

Is there something we can do to investigate this ? My knowledge about the sound-system is very limited...

After reading lots of articles/forum-threads during the last weeks, I removed pulseaudio from my system and all problems are gone !

To clarify that: the pure presence of the pulseaudio-server causes the problems.
It doesn't make a difference if I install additional modules/plugins or not (with xine-pulseaudio-plugin, an additional device "pulseaudio" appears in the KDE-system settings and it works).

Is there anything that could be done to improve the compatibility of Phonon with pulseaudio ?
