[QUOTE="Alberto83, post: 1241411, member: 128278"] If you followed the procedure to determine which bitrate is compatible with both you AVR and driver, you're good to go and you can keep reading. Otherwise, you definitely should check compatibility first and know exactly which bitrate is working with your system. We're gonna add another piece of software in the graph chain for video playback that will obviously introduce a new layer of complexity, so we better be prepared to know exactly which bitrate works and which does not. As said earlier, we need basically one software to configure WASAPI on our system. My software of choice is ReClock from RedFox. You can download it [URL='https://www.redfox.bz/download.html']here [/URL]from the site developer's page. Sadly, it seems the software is discontinued, but really, there's nothing more that they can add to this great plugin. Download and install ReClock. Then open its property page. The installer should add a new link on your desktop "configure ReClock". Configure the Audio Settings software as in the picture below. [ATTACH]196801[/ATTACH] [B]Audio Settings TAB:[/B] [I]Audio Interfaces to use for[/I]: For Bitstreaming enabled and PCM WASAPI, configure WASAPI Exclusive on PCM sources and leave Bitstream to default DirectSound. This will allow to take exclusive control of the audio device for every PCM stream but still use LAV Audio filter for bistreaming (and thus have your fancy leds on your AVR lit). [I] Devices to use with[/I] This pane allows you to bypass the windows mixer default device. This is useful if you have multiple playback devices connected to your HTPC. Since modifying this is dependent from your specific configuration, I might cover it in future posts, based on specific needs. For the purpose of this article, leave them to Default Device as in figure. [I]PCM Output:[/I] This is the tricky part. Here you have to change your Sampling Rate to the Maximum allowed sampling rate you found earlier while playing with your AVR and your drivers. In the screenshot above, my sample rate is 192kHz, which means everything will be played to 192kHz, and [U]those signal with lower sampling rates WILL be resampled to 192[/U]. Now, if you use an HDMI connection to your AVR, you might need to chose 24 bit padded to 32 as format. This is due to the fact that some AVR only accept 24bit as padded 32bit signals. (like mine). You probably need some trial and error here. If you're using an optical connection, you can totally use 24 bit int. For quality, use Best Sync Interpolation first, and eventually change it to lower until it plays the sound correctly. A word of warning. Do not flag "set matching speaker configuration". We want stereo sources to be sent as stereo to the AVR this make Dolby Prologic effective. [I]Bitstream[/I]: Flag Accept Bitstream Formats (not recommended). This will allow bitstreaming bypass. Check Disable Media Speed Correction with bistream audio (recommended), since we're already correcting A/V sync in the LAV audio filter. [B]Video Settings TAB:[/B] Uncheck built in estimator for both media files and DVD if needed. Leave the rest untouched. [B]Advanced Settings TAB:[/B] Uncheck ALL VSYNC corrections, and check "Force ReClock to be loaded instead of Default Renderers" "[I]Application for which reclock is allowed to replace the default renderer[/I]" Check "Only load reclock and show application dialog for defined application", then click Add. Navigate to "C:\Program Files (x86)\Team MediaPortal\MP2-Client" and then select MP2-Client.exe, then for the new entry select "Load Always". [ATTACH]196803[/ATTACH] NB: If you find some stuttering during playback, you can later check "Give High CPU priority to player". Done. Reclock is configured, you can now try it by opening Mediaportal. Fire up mediaportal 2, go to settings -> Players -> Codecs -> Audio Codecs. Chose Audio Renderer, and select "Reclock audio render" from the list. You should be able now to play videos with stereo tracks and send real stereo signals to your AVR even if your windows mixer is configured as a 5.1 system. Test it with multiple sources and check that bitstreaming works correctly, for every format, especially DTS:X and Atmos, and the HD sources. In the next post i'll address specific issues with specific drivers and configurations. Is anyone of you using reclock? If yes, which settings are you using? [/QUOTE]
