Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate—it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.
 
I saw that one forum person had issues with their Western Digital Caviar green hard drive was causing streaming issues, due to the variable spin rate that those drives have.  I have not seen any confirmation of this as of yet, in other threads, but am still looking.  Typically, for computers running software such as Sonar, the faster the drives the better, so whenever possible use drives that spin at 7,200 or better.

Kamn: there are a few things we should go over
 
1- Bios ....there are 24 bios rev's for your board .....M4A78T-E BIOS 3503
"1. Improve system stability.
2. Support new CPUs. Please refer to our website at:
http://support.asus.com/c...t.aspx?SLanguage=en-us
3. Enhace compatibility with some USB device."
 
2- chipset drivers for win7-64 AMD ..  where did you get them
 
3- Western Digital Caviar green hard drive was causing streaming issues, due to the variable spin rate that those drives have..is correct !
 
lets go over your set-up I can also do bios revs if you wish !

I'm at bios 3503. got my chipset drivers from the asus support site for my board.
 
i don't have streaming issues so much as Mackie freezing or not functioning consistently. just now my Mackie was working including transport functions. all of a sudden the transport functions have stopped working. . i can start and stop music from my computer keyboard, and i can use the faders on the Mackie, but the transport functions on the Mackie are not working.
 

Kamd good on bios .. as for the chipset drivers  here.... http://support.amd.com/us...es/raid_windows.aspx#2
 
AMD Chipset Drivers26.4 MB13.44/24/2013 

Disabling power management and anti virus, and verifying/updating updating drivers,  have improved things dramatically. However, sometimes the transport buttons on the Mackie still get "stuck" , aka don't do anything. Seems if I hit spacebar on computer keyboard and play on the Mackie several times together or alternately the Mackie will sometimes start working again. Strange behavior.
 

Kman: see you system is running this firmware update....
 
http://www.mackie.com/products/mcupro/index.html
 
MCU Firmware v4.0.3 (for updating MCU Pros and XT Pros running Firmware v4.0 and higher)
MCU Pro v4.0.3.zip (.ZIP, 256 K)

I followed the instructions and couldn't get the update to work. I'm at 4.0.1.  I put it into the "waiting for firmware update" mode, press play and nothing happens. The mackie is supposed to display some blinking lights during the update but it just sits there with the "Waiting" message. I was on hold with Mackie for over an hour and just hung up from the torturous music loop they play.

No Driver Required for Supported Windows (PC..is the next thing i question.... it didn't work as advertised. The "USB only" thing just didn't work for me so I had to connect the midi cables as well and then it worked

Update. I finally got hold of Mackie tech support and they suggested I use a midi file player found on ssynth.com. It worked. My firmware is updated to 3.0.4 and the transport buttons always work! Playing the Mackie update midi file through Sonar just doesn't work.
