Choppy sound issues + clock remaining behind


Best Answer k3nny, 27 July 2013 - 09:27 AM

You can calculate the FSB from the TSC frequency (found in the very beginning of the log) like Clover does it:

 

2700071520 / 27 = 100,002,648
 
2700020560 / 27 = 100,000,761
 
I would be surprised if you still get the issues with r1936.

Hi Guys,

 

I am having some problems with my setup (check the signature) most of the time the sound is choppy and the clock remains behind (it is now 8:09 PM and it show 6:59 PM) did anyone encounter such problems can they be fixed ?

 

Thank you,

If you have dual boot with windows: http://lifehacker.co...oting-with-os-x. I don't know about the sound.

Choppy sound can be fixed by patching DSDT as described here: http://www.projectos...p?showtopic=564

@Rogiervd: i am not using dual boot i have only OS X on this machine

 

@Gringo Vermelho: i see that they are talking about slow sata speeds over there are you sure i can do the same modifications ?

 

If it helps i can post my DSDT

No reason to post your DSDT, just do the edits as described and see if it helps.

 

Yes, you can do the same modifications, read the thread for more information.

If you're booting with Clover then you may need to specify a different Bus frequency to get rid of those issues.

 

EDIT: changed from CPU to Bus frequency, my mistake.

Hi Ion, you also should boot Clover EFI once, retrieve the BusSpeedkHz value (right after CPU frequency in the wiki) from the boot log, and set it in your config for use in UEFI mode.

According to Slice the automatic detection is not accurate in UEFI mode and I recently had some sound issues because of it myself with 10.9.

 That's the one:

...
Corrected FSBFrequency=100MHz
...

Try setting it to 100000.

I don't know if you noticed that that the plist had the value in MHz, and you've now set it in KHz.

 

100 MHz and 100000 KHz is mathematically the exact same value, so, as long as Clover supports setting this value in KHz, nothing has changed!

I believe that was with legacy boot, where as the UEFI boot may give him a slightly different frequency (more precise, according to the devs).

 

 

Though I'm not sure he booted in legacy mode:

Starting rEFIt rev 1794 on American Megatrends EFI

Try booting with Chameleon if you can, take note of the bdmesg values and try them in Clover.

so far so good seems that the problem is fixed :D

 

@Maniac10 i disabled all the EFI options in the BIOS and let clover boot in normal mode... unfortunately i cannot use chameleon because it doesn't get along well with my GPU :(

The debug line shows a rounded value for the calculated FSB and it is not exactly 100 MHz / 100,000 kHz.

I tried to find a more accurate value in ioreg and here are my results for both modes:

Command:

ioreg -pIODeviceTree -fl | grep FSBFrequency

UEFI automatic detection:

"FSBFrequency" = <a518f60500000000> > 0x05F618A5 > 100,014,245

EFI automatic detection:

"FSBFrequency" = <3aebf50500000000> > 0x05F5EB3A > 100,002,618

Will be using 100003 now and see how it runs.

 

EDIT: Distortions with 100003, reverting back to 100000 that I already confirmed to run fine. 100002 might also work.

If anyone still has problems, try Clover r1931+. It has a more precise algorithm for calculating the BusSpeed.
