Ask for audio playback tips in WO in WATCHOUT FORUM Posted February 23 · Report reply On 5/1/2017 at 6:22 PM, jfk said: You might try this, may or may not help. ... On relatively new computers (including WATCHMAX) with Intel C612 or X99 chipsets there are PCI bus interference problems causing the audio to pop/crack/click. This interference comes when the GPU changes it's clock frequency. This occurs more often with AMD hardware than with NVIDIA cards. The problem is not limited to WATCHOUT and can be triggered in any application as soon as audio and video are played simultaneously. At the moment AMD is working on a solution and hopefully NVIDIA will do the same (Matrox are using AMD drivers). Until the final solution is available, there is an intermediate solution by setting a registry variable. For the WATCHMAX this solves the problem with the internal sound card. With an external sound cards the fix helps but not completely. Clicks can still occur every now and then with several seconds apart. The intermediate solution is: Run regedit Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\4D36E968-E325-11CE-BFC1-08002BE10318\0000 Create a DWORD (32-bit) Value named “ForcePcieLinkSpeed” and set the value to 3 Reboot If you by any chance have a 0001, 0002 or 0003 folder in the 4D36E968-E325-11CE-BFC1-08002BE10318 folder then repeat step 3 in all these folders. Normally a WATCHMAX should only have the 0000 folder. Shame on your timing. There is a complete re-write of the audio sub-system coming to bring it up to date with todays technology. Coming soon, but not soon enough Many devices now working under WDM will gain new function and better operation with the same hardware under an ASIO driver. Hi Jfk do you know if AMD has fixed this issue. I have had this issue on my watchmax ever since I got it 3 years ago. Very frustrating. I run audio now off my production machine witch also has a AMD card in it. I sometimes also get a click sound on playback on the production machine. If I put a Nvidea card in my production machine will it help??? I’ve tried internal sound cards, usb sound cards and recently tried Dante Vertual sound card. I have tried separate Wav files with the same 4800khz. Nothing fixes the issue. Any advice?
