I have noticed that myself on some hardware. It's the Debian alsa/pulse on certain hardware I guess. You can try these things.
1) Delete the .pulse and .pulse-cookie folder in your home folder. Re-login and see if that fixes it.
2) Just disable the login sound (System Settings -> Application and System Notifications -> Event source: KDE Workspace). This will also speed up your login. It's a KDE login and pulse/alsa initialization issue, sounds works fine after login completes.
3) Uninstall "pulseaudio". Don't uninstall all pulse named packages, just pulseaudio and anything else it automaitcally removes will do. then you will be back to plain ALSA, which works very well without pulse. Don't ask, google "ALSA vs Pulse".
Hope this helps :-)

Thanks Euan, removing Pulse Audio worked for me as this has always been a problem for me with Debian on my old-ish HP laptop. now I have clean crisp audio.
Off topic, thanks for this distro, it is the one that will finally end my distro hopping, it has it all (that I will ever need) and I also convinced some Windows die-hards to try it and they are impressed. Excellent work.

I have been playing with Slackware a bit and the sound is good. They don't use pulseaudio. I'm coming to the conclussion it is not that great really. I can't see the benefit of it.
For example, on Slackware; when I play video in vlc and adjust the vlc (application specific) volume, the ALSA master volume is not effected. Other audio apps can have their own volume and yet the master (overall) volume is maintained. ironic, since this was what pulseaudio was designed for. Yet on Kwheezy (Debian), the pulseaudio master volume always changes itself to 100% when you change the VLC volume.
I think in the next iteration (Debain 8 based) I may ditch pulseaudio. Needs some research. Let me know if there are any apps that require pulseaudio.

There is a way to fix it, but the "overprotective" KDE will not let you edit require file. The file is in /etc/pulse/default.pa
find a line : load-module module-udev-detect and add to that line tsched=0
That fixed the scratchy sound, but to do this, you will have to log in as root.
The problem with KDE - it will not let you log in as root unless you edit the /etc/kde4/kdem/kdmrc file. Find line where rootlogin=false and replace with rootloging=true. You will have to boot from another live distro to be able to edit those files. Kweezy live is not in root and will not let you editi it.
I have Kali Linux on usb stick. Boot from usb live and edit needed files. Since, I have root logign in Kweezey- I can edit eny files. Kind of "hard way" to fix the sound. Blame the KDE for that.

There are other, better, ways to login as root. But thanls for the tip on how to fix the issue. Others may find it useful. I ended up disabling the login sound in a more recent version of Kwheezy (i think).

Thanks Ian, that's great news.

Haven't come across any yet, all the audio seems fine to me so far.
