Intermittent sound with 5.1 setup

Hi there everyone!,

I´ve recently adquired a HDMI converter to HDMI + Audio and used it to connect my Pi to my home cinema via spdif. If I have a 2 speakers setup there is no problem (but just stereo sound, obviously), but if I set up to 5.1 the sound is horribly intermittent. I have a Pi B+ overclocked and booting from a pendrive. Any idea??

Thanks and best regards!

Nevermind, it was a problem with a buggy installation. It´s solved now!
