Im having a bit of an issue with my E10 - it's been reported before but I think there's something I'm missing here.
I have a early version of the E10 .. bought in nov 11. If I go through the sample rate / bit options I hear a certain BUZZ in the headphones. However if I choose 24/96 or 16/96 nothing is heard. So you might think : why not leave it on 24/96 and call it a day? Well I am in a period when I test some speakers I recently got and I kept trying it out with either my sound card ( a pretty old but still awesome Hercules Fortissimo IV - envy24 ) or the Fiio. So I installed ASIO4ALL and WASAPI on foobar trying to squeeze as much quality as possible from the little FIIO. When the output is set to either Wasapi or ASIO I get the buzzing noise no matter what sample/bitrate I try. I have also installed the FIIO ASIO Driver, thinking it might help.
However, if I use ASIO4ALL as output when a song is played the buzzing stops but it's pretty obvious between tracks. I usually have mostly FLACs 16/44.1 and some 320kbps mp3s. It's the same with either type of files. If I use WASAPI - the buzzing is present all the time, it doesn't matter if a song is playing or not.
The headphones I am using are AKG K550 and very rare the Brainwavz ProAlpha IEMs which make the buzzin even more obvious. The Gain on the Fiio if off and the volume I use it on is at about half ( 5 out of 8 ).
This is very annoying, if nothing is playing I hear it - what's funny is that if I double click a folder it's gone. Then comes up if I open winamp for example or if I double click a song on foobar it starts again for 1-2 sec till the song starts and then shuts up again. If I stop the song or it reaches the end it's back on. And then I do the double click in windows explorer so it's gone again. So it seems that it's triggered on and off by a certain type of song that is played ( when I open a folder the windows plays a short click sound ).
Is my unit defective? What's important is that it's not audible WHEN a song is played but that is only true if ASIO4ALL is used. If Wasapi is used it's there all the time. I also have a pretty new Sony Vaio F2 series laptop and it does the exact same thing on it too so it's not a computer issue for sure.
But if I use DS output - there are no problems , unless I screw up into the sample/bit options.
Can you guys please do a little test and see if your FIIO copy does the buzzing when changing through sample/bit options for starters? It could help to have the volume a bit higher as maybe your headphones are not sensible enough.
