RE: Recording issue on sansa clip zip

I was using:
c3c2c91-150421
and it was happening with that version

I just updated to:
47d0537-150518
and i just tested and found that the problem still seems to exist with this version.

I also own a Clip Zip. I hadn't noticed that problem, so I tried to 
replicate your issue on mine just now. Mine works okay during a 
recording when the volume is adjusted with the side buttons. I tried in 
MP3/192k/Stereo, and also left channel mono/16k/Wavpack. On my unit, the 
peak meters continue to register, I continue to hear monitor audio in my 
earphones, and the volume indicator starts moving up or down as expected 
given which button I was pressing. I can also change the volume with the 
4-way pad too.

(I still have the problem where the clip indicators never actually 
indicate, despite the recorder clipping like crazy if the gain is too 
high, but this is another matter.)

(My Clip Zip's recordings also exhibit horrid DC offsets, more in the 
right channel and less in the left. It's mono from the builtin mic 
anyway, so this is why I normally set it left-channel mono. Then I have 
to be sure to remove the DC offset in post, if I'm going to use the 
recording for anything more than personal notes. This too is another 
matter, and likely a fault the the Zip's hardware design, not anything 
to do with Rockbox.)

Perhaps it's been addressed in my version of the firmware. I haven't 
been using the standard releases since I noticed the Opus codec causes 
the device to crash sometimes when seeking is attempted (which remains 
an outstanding bug). I've been occasionally refreshing my unit with the 
development daily builds. My version at present is: 2cdfc43-150115

What version are you using? Have you tried one of the daily builds?

Regards,
Andrew
