[QUOTE="Sinbe, post: 750457, member: 62129"] I'm having problems with 2.0 to 5.1 conversion which is disabling (?) time stretching. Here are couple of pictures with refresh rate set to 100Hz. Video is 24fps and the "max bias" is at 1,1 so 24 to 25fps should be working (and is when audio left at default). [B][URL="http://oi54.tinypic.com/1zg9f0i.jpg"]100Hz, 24fps video, 2ch[/URL][/B] [B][URL="http://oi54.tinypic.com/smwr3t.jpg"]100Hz, 24fps video, upmixing to 5.1[/URL][/B] The same thing happens when I set the output channels to anything else than 2.0. Even 1.1 won't work even though the number of channels stays the same. I can also see there's a difference that in one of the pics MP seems to load "default direct sound device" and in the other it doesn't. I used wrong refresh rate in the testing to show the problem more clearly. When using ~96Hz, I get duplicated frames few times a minute and an annoying micro stuttering all the time. I'm using v0055c version of the dshowhelper with the modified audio renderer found in the other thread, but I had the same problem with the v20 found in this thread. Edit: It only happens on my Soundblaster X-Fi and not my integrated Realtek so maybe my soundcard can only support WASAPI with 2.0 audio? Is there a way around this somehow? [/QUOTE]
