I've had the D1 for about six months now, and I'm awfully tired of the clicking/popping when switching songs/movies/etc. I've searched this thread and found that quite a few of you are experiencing the same issue. Is there any fix at all? I'm not really an audiophile, and $200 was a big investment for me to put up with quality this shoddy.
- Using USB, the pop is moderate in volume and almost entirely (if not entirely) in the left channel. It also only occurs maybe 30-50% of the time I switch files in foobar, VLC, etc.
- Using coaxial from my onboard S/PDIF, the noise is a bit quieter and sounds more like a short period of static than a discrete pop. It can be heard in both channels, and occurs the vast majority of the time I switch files.
I do not own an optical cable, so have not tried that yet.
I'm running Win 7 x64, default driver for USB, and have the output universally locked at 16/44.1 through the control panel for S/PDIF. So, it's hard for me to imagine that the clicking is because of changing sample rates, as some have suggested.
Also of interest: I made some silent WAV files, put them in foobar, and started hitting "Next" repeatedly. There were very few pops then, whereas switching from a loud rock song seems much more likely to produce a noise. This makes me wonder whether it could be a problem with the digital-analog conversion itself, rather than sample rate?
EDIT: Just to clarify, the clicking is in the audio itself, not mechanical noise from the DAC. I just hooked it up to my standalone DVD player for the first time, and switching tracks on a CD playing through that revealed the mechanical click that some of you have mentioned, which is a completely separate issue.
