Audio/Video Sync & Stuttering Issues

2 posts in this topic

Recommended Posts

Ok so I'm looking for a little help with my Lion install.

 

Here's the story:

 

I've been running 10.6.7 on my AMD machine for the better part of a year with absolutely no issues. I mainly use my HackPro for video editing in Final Cut Pro X, so when the first AMD kernels were released with 32bit support only, I had to stay away (FCPX is 64bit only). Not until recently have I started working on installing Lion & Mountain Lion. And so far, I just can't win :(

 

With Mountain Lion, I had graphic corruption caused by the amd_kernel. Understandable, I told myself, and decided to roll back to 10.7 and give that a shot, as I heard there were several working kernels with full graphic support for my HD 5750. I was able to get up and running in no time at all, found working kexts for my graphics and network, sleep is working with no issues, shutdown/restart, the whole nine yards. I'm able to boot in full 64bit mode or 32bit/64bit userland, and FCPX opens and runs perfectly well.

 

Here's the issue:

 

Any sound that I play on my machine starts off with a brief stutter. Video sources such as YouTube and Netflix play fine after the stutter goes away, which is well and fine. The problem I'm having is when I'm playing video in Plex Media Center, or when I've opened a project in FCPX and start playback, the video is behind the audio, falling completely out of sync. It seems like the video is playing in slow motion, and the audio is playing at full speed. I have had no issues whatsoever with audio up until this point. I use a Tascam USB audio device, which works in 32bit only, and I've used VoodooHDA to enable my on board audio. With either device, the audio issue is the same.

 

I've tried using busratio=15 as a boot flag, I tried enabling/disabling SSE2 in VoodooHDA prefs, I've tried creating and compiling a DSDT (never used one before, and couldn't find any patches for the one I made...), and nothing seems to be helping. I've also tried a number of different kernels to no avail.

 

I'm tired of being stuck on Snow Leopard. I'm trying and trying to get this working so that I can use it as my full time OS, but I just can't seem to shake the issues. If it's not one thing, it's another.

 

***EDIT: I also have an nVidia GTX 550 ti, GT430 8300GS on hand if they would make the Lion process any easier. Thanks again.***

      How to make AppleHDAController load on Ryzen boards?
      Rename(/add) your audio controller to your DSDT/SSDT as HDEF Add a _DSM method to your HDEF device with layout id 1 Patch the AppleHDAController binary, because it has a static table containing the supported PCI Vendor/DeviceID pairs and it also checks the VendorID against known values. As an example I provide a dif file and patched 10.13.3 binary, but if you want to I can patch the binary for other versions.  
      After AppleHDAController loads to actually get sound working you need to patch AppleHDA.kext for the codec on your board. First I tried to use Lilu+AppleALC for this task, but for some reason it refused to work. (I might look into it later why) But for the time being it was easier to use toleda's cloverALC script for that, but to make it work I had to change(/remove) the specified location of the HDEF device from the script. And for some reason it also required me to mount the EFI partition manually.
       
      Change this:
      if [[ $(cat /tmp/HDEF.txt | grep -c "HDEF@1") != 0 ]]; then Into this:
      if [[ $(cat /tmp/HDEF.txt | grep -c "HDEF") != 0 ]]; then

      Hi, I tried during last 4 days almost everything but now I call for help. I have RX560 running on 10.13.4. Previously I was running it on 10.12.6 and had the same problem, but after waking from sleep my thiord display came to life, but it is not working anymore on 10.13.4. Without or with Lilu & Whatewergreen my system correctly recognize my gpu as RX560 but only 2 of 3 displays are displaying content, third display is black but recieving some signal. When I change cabling and connect only two, any combination of 2 displays is working. System profiller and system preferences are sayin I have 3 displays connected.

      Please can somebody help me to figure it out?
      Thanks a lot in advance. Tried to upload my ioreg but it is greater than 10MB allowed for me :(

      Hi, i recently set up High Sierra on my AMD computer with the help of the amdosx community (i actually used an installer just to confirm that something would work in the first place before i spend hours for nothing, i can and could have downloaded High Sierra the "legal" way).
      However the graphicscard is recognized properly, the 6gig are recognized and i have no artifacts and no screen tearing with the official nvidia webdriver,
      but unfortunally, dark colors have horizontal dark stripes in them and specific bright colors like on left bar of system windows such as settings do flicker like low fps.

      I only used the clover on the flash drive for now and i'd like if it's worth digging deeper of if i should just forget about it as it is a common nvidia problem on macOS.
      Would be amazing to know.
       
      Closer machine infos:
      * High Sierra (misses a recent minor patch as my network is veeeery slow and i got this nvidia issue anyway so i mainly jumped back to linux)
      * AMD fx8350
      * Asus Sabertooth 990fx Ref. 2.0
      * NVIDIA GeForce GTX 1060 6GB
