It works for me.

Thank you so much for the port to the Sansa Clip Zip. To be honest, as I researched which player to purchase, one of the biggest factors was whether Rockbox was available. This port allowed Sandisk to get a sale that day.
I've been using these builds (and updating regularly) for almost a month now. I've noticed some strange playback issues with the newer builds, which I first mistakenly attributed to a bad set of IEMs. Basically, the audio was almost cutting out sometimes or was going back and forth between the left and right -- well beyond what some stereo music does.
As a test, I played the song from the Sansa firmware and it sounded fine. I reverted back to an older build of Rockbox, and it too sounded great. Below are details about versions, etc. Hopefully something sheds some light on the issue.
Consistent
Test Song: Lo Fidelity Allstars - Battleflag (FLAC - yes, I know it's overkill for a PMP)
Headphones (IEM): MEElectronics A151
Volume: -50 to -70 range for each test
Versions
Sansa 01.01.18 - sounds good
Sansa 01.01.17 - sounds good
Rockbox r31233 (latest) - problem occurs
Rockbox r31209 - problem occurs (I had hoped the changes to mpc were the reason, so I picked one before those changes in svn, but still no luck)
Rockbox r31107 - sounds good
Rockbox r31049 - sounds good
I haven't tested each and every version between r31107 (known good) and r31209 (known bad) but I hope this helps somehow.
Does anyone have any ideas? Would trying the versions between help somehow?
To be clear, I never changed any settings like EQ or anything, so that isn't the culprit either.
Thank you again for all of your hard work!

Yes, r31207 (fixed 5.1 mixing for FLAC files) seems a bit off for stereo.

Thank you, saratoga. I just tried r31194 (the last build for the Sansa Clip Zip prior to r31207) and it sounds great! The next release is r31209 which I already tested and found to be bad.
I appreciate your insight. I hadn't considered that changes for 5.1 FLAC might affect regular stereo FLAC too like the one I was testing with.
I'll still test new builds (especially if they mention those type of changes), but it looks like r31194 is going to be the sweet spot for me for now.
You rock

A couple people have confirmed that the new bootloader works as expected. I guess we should tag it so that people can use rbutil.

I'd like to wait a bit to see USB works great so we could enable it in bootloaders and have mkamsboot always boot rockbox even when powered by USB.
