Again, after upgrade to Xubuntu 13.10 (64bit) I have faced few issues with sound. Luckily all those were possible to easily fix.

Crackling microphone (in all application, most in Skype)
As described here, edit file
/etc/modprobe.d/alsa-base.conf
sudo mousepad /etc/modprobe.d/alsa-base.conf
Add to the end of the file:
options snd-hda-intel position_fix=3
Note: Some suggest to add options snd-hda-intel position_fix=1
Skype – no sound o distorted sound
Distorted sound or no sound at all in Skype can be fixed by modifying file
/etc/pulse/default.pa
sudo mousepad /etc/pulse/default.pa
Find line with
load-module module-udev-detect
and change it to
load-module module-udev-detect tsched=0
This fix was found here.
Sound (volume) indicator disabled
This is known issue in Xubuntu 13.10 release.
Until it is fixed, you can use this.
Edit file
/usr/share/dbus-1/services/indicator-sound.service
sudo mousepad /usr/share/dbus-1/services/indicator-sound.service
comment line
#Exec=/usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service
and add new line after it
Exec=/bin/sh -c 'if [ -n "$(ps -U $USER | grep xfce4-panel)" ]; then /usr/lib/indicator-sound-gtk2/indicator-sound-service;else /usr/lib/$(arch)-linux-gnu/indicator-sound/indicator-sound-service;fi'
