Panamamax Posted October 4, 2016 Share Posted October 4, 2016 Good day... i cannot get rid of stuttering Audio. i followed this installation guide: i further bought a USB sound device that i can see in my Audio settings... hoping that it will fix my stuttering audio... however no improvement. I can choose where i want to output my Audio, everywhere including the optical output and the USB outputs i can output the music, however all of them have stuttering sound with the sound coming and going 2-3 times per second... any idea how to fix it? couldn't find much information about stuttering sound... my system is 10.12 on a Supermicro X10SRA-F board that runs the ALC1150 chip...

Panamamax Posted October 4, 2016 Author Share Posted October 4, 2016 Further followed the following guide for the installation of the VoodooHDA with the same results... Stuttering ...Anybody? Link to comment Share on other sites More sharing options...
okrasit Posted October 4, 2016 Share Posted October 4, 2016 sysctl -a | grep tsc Verify machdep.tsc.at_boot == machdep.tsc.frequency 1 Link to comment Share on other sites More sharing options...
Panamamax Posted October 4, 2016 Author Share Posted October 4, 2016 Thank you for your feedback! i assume " sysctl -a | grep tsc " is a command in Terminal? How do i verify Verify machdep.tsc.at_boot == machdep.tsc.frequency ??? Thank you! Max Link to comment Share on other sites More sharing options...
okrasit Posted October 4, 2016 Share Posted October 4, 2016 If they differ, you'll have to compensate with Clover's BusSpeedKhz! That is, if u r using some unsupported cpu! Link to comment Share on other sites More sharing options...
Panamamax Posted October 4, 2016 Author Share Posted October 4, 2016 yes you are right... the frequencys are different.. thats what terminal send out: net.pktsched.verbose: 0 machdep.cpu.tsc_ccc.denominator: 0 machdep.cpu.tsc_ccc.numerator: 0 machdep.tsc.nanotime.generation: 2 machdep.tsc.nanotime.shift: 0 machdep.tsc.nanotime.scale: 1594410217 machdep.tsc.nanotime.ns_base: 0 machdep.tsc.nanotime.tsc_base: 219744514948 machdep.tsc.rebase_abs_time: 80834478698 machdep.tsc.at_boot: 1995381892 machdep.tsc.deep_idle_rebase: 1 machdep.tsc.frequency: 2693765538 and now whats the next step to compensate it? Thanks for your help! ...Max Link to comment Share on other sites More sharing options...
okrasit Posted October 5, 2016 Share Posted October 5, 2016 You've got to check Clover for the value you currently have but I'm guessing it's near 100000. So 1995381892/2693765538 * whatyouhavenow ~= 74074. Put that in your clover config.plist! Or type it in on boot in Clover's options -> CPU -> bus freq.

Panamamax Posted October 5, 2016 Author Share Posted October 5, 2016 Good day! currently the field is empty... so what do i have to fill in there? Link to comment Share on other sites More sharing options...
okrasit Posted October 5, 2016 Share Posted October 5, 2016 You should start with 74074 and then do another round of fixing until you get it right! Link to comment Share on other sites More sharing options...
Panamamax Posted October 5, 2016 Author Share Posted October 5, 2016 Perfect... Sound is now working! Thank you Link to comment Share on other sites More sharing options...
Panamamax Posted October 6, 2016 Author Share Posted October 6, 2016 Turns out that the bus speed fix is killing my cpu speed... in the about this mac i t shows 1,5ghz instead of 2 and the performance reallz sucks... any idea how to have both... sound and perforance???

okrasit Posted October 6, 2016 Share Posted October 6, 2016 It was actually running at that speed before too, your clock was just running slow! The issue is that you've got no turbo. There's two ways to handle this: Bus Speed & https://www.dropbox.com/s/102fk4i8xv86466/msr199withUncore_max.kext.zip?dl=0 OR Use piker's kernel patch -> xcpm.

Panamamax Posted October 6, 2016 Author Share Posted October 6, 2016 hmm this sounds very strange.., only by applying the Bus Speed, my performance changes from this to that... if i remove the frequency the speed goes up again... will try and see if adding the msr199 kext will re-establish my performance once i change the bus speed tonight...

You see, if you don't compensate the TSC frequency error, one second on your computer now actually lasts for 1,35s! That's exactly the multiplier for the scores... It's not faster it's just WRONG. So, you're not re-establisishing performance, you're getting it right! Link to comment Share on other sites More sharing options...
Panamamax Posted October 6, 2016 Author Share Posted October 6, 2016 hmm... going to make some tests tonight... cause when its true what you say is that the actual power is the same... but i believe it feels slower.. i will make some tests and render a video file again the clock to see if there is a difference... also... why does the CPU frequency drop to 1,5 instead of 2?

It doesn't really drop, it just reads wrong due to multiplier times busfreq calculation... It doesn't matter at all. You could do this in terminal to see how much your clock drifts instead of rendering... ntpdate -d somentpserver run it a few times and you'll see...

Panamamax Posted October 6, 2016 Author Share Posted October 6, 2016 Hey! i have done the following tests: I added a 4,2Gb h264 4K DCI file from a phantom3 professional to iFFMPEG to cenvert the clip in Pro Res. i have done this without bus speed and kext, with bus speed onlz and with bus speed and kext 1. Without bus speed and kext: 5:45min 2. with bus speed, without kext: 5:50min 3. with bus speed and kext: 5:46min i assume that it really does not matter at all... what should do the kext? i cannot recognize any difference in Cinebench i now run 1946cb insted of 2679cb i had before.... does this mean now that the 1946 is the real value and the 2679 is the wrong fake value calculated wrong having a wrong system clock? Further if i run sysctl -a | grep tsc i now have: net.pktsched.verbose: 0 machdep.cpu.tsc_ccc.denominator: 0 machdep.cpu.tsc_ccc.numerator: 0 machdep.tsc.nanotime.generation: 2 machdep.tsc.nanotime.shift: 0 machdep.tsc.nanotime.scale: 2147485795 machdep.tsc.nanotime.ns_base: 0 machdep.tsc.nanotime.tsc_base: 214561511488 machdep.tsc.rebase_abs_time: 106283172869 machdep.tsc.at_boot: 1995378212 machdep.tsc.deep_idle_rebase: 1 machdep.tsc.frequency: 1999998000 is this sufficient adjusted or do i have to modify my 74074 bus speed again? Thank you! Max Link to comment Share on other sites More sharing options...
okrasit Posted October 7, 2016 Share Posted October 7, 2016 That's pretty close, but 73902 will put you right on the spot! Just load the msr199.kext and you'll also get turbo! And yes, those results were wrong as you had your clock running at wrong speed. Make sure you have c1e or "halt to mwait" enabled in your bios!

Panamamax Posted December 8, 2016 Author Share Posted December 8, 2016 good day... im working on a dual build and time runns crazy . this is what i get: i have to set 7,25 in the bus speed???

Panamamax Posted February 13, 2017 Author Share Posted February 13, 2017 Good day, tried to revive my dual project after some time but have the same problem with the running clock... One minute takes about 8,2 to 8,5 seconds at the moment. i changed the bus speed to 100.000 and this is what i get: Maxs-Mac-Pro-2:~ max$ sysctl -a | grep tsc net.pktsched.verbose: 0 machdep.cpu.tsc_ccc.denominator: 0 machdep.cpu.tsc_ccc.numerator: 0 machdep.tsc.nanotime.generation: 2 machdep.tsc.nanotime.shift: 2 machdep.tsc.nanotime.scale: 2684354560 machdep.tsc.nanotime.ns_base: 0 machdep.tsc.nanotime.tsc_base: 139030667766 machdep.tsc.rebase_abs_time: 340342613280 machdep.tsc.at_boot: 2893622398 machdep.tsc.deep_idle_rebase: 1 machdep.tsc.frequency: 400000000 Maxs-Mac-Pro-2:~ max$ Link to comment Share on other sites More sharing options...
Panamamax Posted February 15, 2017 Author Share Posted February 15, 2017 All right... i found my mistake... had still the 74000 in CPU section that killed my timing.... now seams to run OK... Link to comment Share on other sites More sharing options...
