Thanks for the feedback Dennis. I also contacted TASCAM, talked to Robbie, and mentioned this was an issue not just on my recorder but it was mentioned in forums quite a bit. He came across as jerk, laughed as I mentioned others had this issue, and didn’t believe this was a problem (it was the first he ever heard of it). I mentioned that I have tried two cards on their approved media list and both have this issue and he told me to try another SD card. This is not an SD card issue, it is a fault with the DP24 and DP32 that could probably be fixed with a firmware update, but employees like Robbie believe it is user error, and it seems TASCAM does not want to put out more firmware updates or address this issue. His solution was - if a third card on their approved media list did not work - send it in so they could check it out. I also sent TASCAM an email about this issue and have received no response. It appears their customer service sucks! My DP24 is no longer under warranty and I don’t want the hassle and expense of sending in the unit, when it could be easily tested and fixed by TASCAM.
Dennis - are you recording at 16bit/44.1 khz or 24bit/44.1 khz, or something else? As I said, my issues happen at locate points within the song and the spikes/pops are not recorded, that is, if I playback or record the song from beginning to end there are no pops. Do you get spikes if you do this? I did notice if I use the repeat function, through the spike locations, the pops are still there but not as loud. Very weird.
Keep us posted on your results and best of luck!
