This is my first post here so im new.
I have this issue when listening to music on my PC with AKG K550, In some parts of certain songs there appears this mild crackling alongside with the music, they are mostly very bass heavy parts always. The sample rate is correct. Tried to re-install sound card driver, tried different sound card, tried different PC. tried with different file types (320kbp mp3, flac, even 128kbs mp3) Its always the same parts of same songs. I listen music with Winamp and I use its EQ and I also use EQ from sound card. sound cards I tried were Asus Xonar DG 5.1 and onboard RealTek sound card. I noticed that most of the songs that crackled were FLAC files. I get the flac files from ripping CDs with Winamp flac encoder.
What this problem might be?
Thanks for your time.
