[SOLVED] Distorted sound in video and GUI sounds

[aitor]

Thank for your answer.

I have no HUB. The connections are:

Rpi USB1: USB HD (with their own power supply)
Rpi USB2: Wifi dongle.
Rpi HDMI: TV

That's all.

The power supply is this:

The problem was solved by itself today. I am thinkin that, if is a power supply related problem, maybe because I have used a phone power supply instead the Rpi's.
