		+	Hi,
		+	When I said HW, I would say board DSP; sorry. From the user manual, http://dlcdnet.asus.com/pub/ASUS/Audio_Card/Xonar_D2-PM/E7807_Xonar_D2-D2X.pdf
		+	we can read p30 6.2.1
		+	[...]
		+	Even if your setting differs from audio source's sample rate, the Xonar D2 engine will do super high fidelity sample-rate-conversion with double floating-point filter, which can reduce total harmonic distorsion (THD+N) by -140dB.
		+
		+	Can we imagine to activate such sample rate conversion and remove pulse audio up-sampling ?
		+	Thanks

		+	== Xonar D2 : resampling processing by the board ==
		+
		+	Hi,
		+	You have done a wonderful job. I've just put the Xonar D2/MP in my PC, desactivate internal sound chip, then restart and the sound was out at the first launch...(Ubuntu 12.10).
		+	I'm using pulseaudio.
		+	My question is about the capability of the board to do digital stream resampling internaly so at 0% CPU penalty and high quality.
		+	Is it a way to activate internal resampling ?
		+	Thanks in advance and again great job!
		+	cheers
		+	Alexandre.

−	~~The one thing that seems to be missing is the ability to sync audio and video. I have an X-Meridian sound card. :-D I am using a Hauppauge HVR-1800.~~
−	After getting all of the right modules in place, I still had no sound. I spoke to the folks at Hauppauge. They said: ( /dev/video0 ) is raw analog video, audio currently not supported. Instead, let the user use the SECOND video device ( /dev/video1 ) -- that is hardware mpeg2 encode audio + video program stream.”
−
−	~~I said great. So I activated the MPEG2 codec for mplayer. But Mplayer kept crashing almost immediately if I ran it using "mplayer /dev/video1 -vo xv".~~
−	If I ran it with "mplayer /dev/video1 -vo xv -nosound" The video seemed to run forever. So I tried " mplayer /dev/video1 -vo xv -cache 16384." I then had both audio AND video until the cache ran out.
