[Samsung Epic 4G Touch] t0mmyr:
Just to update, I tested listening to the same flac album I always listen to to test the skipping bug on my way home from work today...I lost count of the number of skips past 5 within the 1st song, it was unbearable. I was running stock settings, which on this rom appear to utilize the ON DEMAND governor.

thanks, I took your advice and tested each governor and the same music files to see if they helped and for reference I'll post what I found on XDA describing how each governor works and in red will be my comments and test results:

Pegasusq Governor:

The Pegasus-q / d is a multi-core based on the Ondemand governor and governor with integrated hot-plugging.

Ongoing processes in the queue, we know that multiple processes can run simultaneously on. These processes are active in an array, which is a field called "Run Queue" queue that is ongoing, with their priority values ​​arranged (priority will be used by the task scheduler, which then decides which process to run next).

To ensure that each process has its fair share of resources, each running for a certain period and will eventually stop and then again placed in the queue until it is your turn again. If a program is terminated, so that others can run the program with the highest priority in the current queue is executed.

I was able to produce 3 skips while playing 3 FLAC files

Conservative Governor:

This biases the phone to prefer the lowest possible clockspeed as often as possible. In other words, a larger and more persistent load must be placed on the CPU before the conservative governor will be prompted to raise the CPU clockspeed. Depending on how the developer has implemented this governor, and the minimum clockspeed chosen by the user, the conservative governor can introduce choppy performance. On the other hand, it can be good for battery life.

The Conservative Governor is also frequently described as a "slow OnDemand," if that helps to give you a more complete picture of its functionality.

I observed skipping sounds while playing 1 FLAC file

Userspace Governor:

This governor, exceptionally rare for the world of mobile devices, allows any program executed by the user to set the CPU's operating frequency. This governor is more common amongst servers or desktop PCs where an application (like a power profile app) needs privileges to set the CPU clockspeed.

This governor worked the best for me, I haven't been able to get it to skip yet and am continuing to listen to the same album from beginning to end while I type this. However I don't know how this Governor really works or trust it. At first my CPU Frequency never changed from 500MHz, it didn't go up or down, my phone reacted smoothly and music played great. I rebooted and now my CPU Frequency appears to be stuck at 1200MHz, at least the performance tab shows its been at 1200MHz for 95% (24 minutes this session). I let my phone idle trying to see if it would drop or go into Deep Sleep and have a feeling if I run this all day tomorrow my battery life won't be as good as it was today which was excellent! AHH! just heard it skip :/ But 1 skip in 20 minutes is acceptable to me. I'll try this Governor out longer tomorrow and see how daily use goes.

Powersave Governor:

The opposite of the Performance governor, the Powersave governor locks the CPU frequency at the lowest frequency set by the user.

OMG this Governor sucks!! It locks the CPU Frequency to 200MHz by default on this ROM (due to using stock minimum freq of 200MHz and max of 1200MHz). Music skipped, menus lagged, open apps took forever, unlocking lagged. I suppose the only reason I would ever use this Governor were if I were stranded somewhere without power and had to conserve my battery for the longest time in hopes to get rescued in the event of an emergency, otherwise I'd pull it from my roms if I could, I'll never use it again.

OnDemand Governor: (set by default)

This governor has a hair trigger for boosting clockspeed to the maximum speed set by the user. If the CPU load placed by the user abates, the OnDemand governor will slowly step back down through the kernel's frequency steppings until it settles at the lowest possible frequency, or the user executes another task to demand a ramp.

OnDemand has excellent interface fluidity because of its high-frequency bias, but it can also have a relatively negative effect on battery life versus other governors. OnDemand is commonly chosen by smartphone manufacturers because it is well-tested, reliable, and virtually guarantees the smoothest possible performance for the phone. This is so because users are vastly more likely to ***** about performance than they are the few hours of extra battery life another governor could have granted them.

This final fact is important to know before you read about the Interactive governor: OnDemand scales its clockspeed in a work queue context. In other words, once the task that triggered the clockspeed ramp is finished, OnDemand will attempt to move the clockspeed back to minimum. If the user executes another task that triggers OnDemand's ramp, the clockspeed will bounce from minimum to maximum. This can happen especially frequently if the user is multi-tasking. This, too, has negative implications for battery life.

FLAC skips pretty badly with this Governor but phone performance is excellent and battery conservation was excellent.

Performance Governor:

This locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle. Race-to-idle is the process by which a phone completes a given task, such as syncing email, and returns the CPU to the extremely efficient low-power state. This still requires extensive testing, and a kernel that properly implements a given CPU's C-states (low power states).

This Governor locks CPU Frequency at 1200MHz, the glass screen of my phone began to get noticeably warm after a while (with the screen off), I was able to produce skips after my 2nd FLAC music track, I would rank this #2 in terms of audio stability, but feel this one would drain my battery the fastest during the day.

My results feel inconclusive, I suppose I can run my favorite governor (pegasusq or ondemand) during the day and when I plan to listen to music just switch to USERSPACE, then switch back when I'm not. I really do love 4.2.2 and this PAC build is awesome!!!!

FYI, I'm using a genuine Samsung 32GB Class 10 MicroSD card formatted to fat32 (can't remember if I left cwm format last or while connected to windows via usb adapter after running dispart>clean on it but I've wiped it a few times trying to diagnose this in the past, have also copied the same FLAC album to internal sd card in hopes it was faster but still get the same skips on either sd card depending on what rom I'm using, no problem in cm9b)

I didn't mess with I/O Handler, any other suggestions or tips?

BTW, love the new low battery sound in this rom, made me realize how much I hate the old sound...lol. Thanks Sniper, I hope a fresh BB build is on the way, 1/29 has gotta be my all time fav.
