rockbox ipod-video sound is distorted

I converted my ipod video to 30gb flash drive. Rockboxed it but now many files are distorted. With or without EQ. Using Brainwavz B2's. Sound and files are fine on my Sansa Clip + and Zune hd 30. Any thoughts or suggestions would be greatly appreciated.

I am assuming you had rockboxed HDD before the flash drive swap. If you didn't have the distortion with the rockboxed HDD, then I would guess the problem is with the flash drive or the combination with the rockbox. Did you try to listen to music using the Apple stock firmware to see if the distortion has anything to do with the RB?

After the 2nd HDrive went bad a couple years ago, I put the non Rockboxed Ipod in a drawer and forgot about it. Recently installed the flash drive and Rockbox.  I tested a couple of the distorted files on the stock IPod and there is no distortion.  Not all files are distorted on the RB'd Ipod, maybe 20%, and these are fine on Zune and Rockboxed Sansa Clip +. Hmm.

Sounds like you got a bad drive if the distortions also exist with the apple stock firmware.

Thanks for all your thoughts Dminor. Distortion does NOT exist with apple stock. But, Maybe I'll try another flash drive anyway..

When you say apple stock, are you talking about with the stock HDD or firmware? What I am saying is with the flash drive you have installed, boot the ipod to the apple firmware and play the same audio file to see if any distortion.

Sorry I wasn't clear.  I did boot to ipod with flash drive and apple firmware, played the same audio file and there was no distortion. Distortion seems to be only with rockbox, ipod, and flashdrive. and it doesn't matter if I use rockbox EQ'er or not.

Huh interesting. Based on your descriptions, I think the problem is not necessarily due to a bad flash drive. It's just this particular flash drive does not work well with the rockbox. Yeah I would say try another type of flash drive that has proven working well with rockbox.

 

What's the brand of the flash drive you used?

You well may be right. I'm using Transcend 32 GB 133x . The only other path I can think of, (probably a long shot though) is to uninstall RB and then re-install.

Definitely try that before anything else. After uninstall, I'd dump the folder as well and start from scratch. I don't have this player so if that doesn't make sense on the ipod, please excuse.

Thanks Goodvibes. It seems like the thing to do first - so I will uninstall, and start clean. We will see....

Dude take a look at this list  (thanks to Steve) and it does seem to report a problem with the flash drive. Not sure that problem has contributed to the distortion with rockbox.

I did Dminor. It's for a different problem. But -- I uninstalled RB, deleted all music files, then re-installed RB and music files. Well, now the distortion is with files that weren't distorted before. So, I guess that points to the Transcend Card. (by the way it only distorts MP3's, not FLAC's). At some point I'll try a new one. Thanks again.
