Yes.

I don't know, as I do not have a Gigabeat, but it will certainly make it better. Just try it and see ;)

Remember the Gigabeat port is very new and still being optimised daily, so hang in there, it will get better!

If you want to get a better view, go to [Menu]>Info>Debug (Keep Out!)>View audio thread

The top line is the PCM buffer and should fluctuate around the 'full' end all the time, as data is transferred in from the codec buffer (the second line).

If the PCM buffer reaches empty, the music will start to skip.

The codec buffer empties until a 'watermark' level is reached and then it refills from the disk.

I find it quite interesting to watch, especially for some high bitrate oggs which my H120 struggles to decode fast enough, but maybe I'm a sad geek ;)

sloth:
The most likely cause of audio skipping is a mismatch between the new bootloader and the new rockbox.  If they do not match, you will almost certainly see skipping, and your player will be slow in all things (menus, for example.)

Mad Cow:
Peak meters don't even faze the Gigabeats 300mhz CPU. ;D I've heard it's because of a bad bootloader like sloth said.

sloth:
I would add: it is unlikely that the bootloader will change any time soon, at least in any way that will require it to be lockstep with rockbox itself.  Once you have the new bootloader and a post January 12 rockbox, you should be good to go, for a while.

PCpr0gramer:
ah! it was the bootloader. I was getting so frustrated; I had my wps code down to three lines and I was still getting skipping. I hadnt noticed the slowness in the menus until I downloaded the new bootloader(found it on the wiki page). Its a screamer. Thank you everyone.
