[SOLVED]Problem with sound in HDMI

Hello good society of Arch
Now I have problems with sound from HDMI. I use Arch as an tvPc, wasting movies and tv shows on it. I use ALSA and it works well, except of a few files that I have, then there is picture but sound is either twisted or not played at all. It does not matter whether I use vlc or mplayer, I'm experiencing the same problem.
I have not found anything about this with google, other problems have been either hdmi sound working or not, not like it is with me, sometimes it works and sometimes it don't.
I know that the files are ok, I can play them in anther pc I have (also using Arch on that pc).
Does anybody know what the problem might be? What do I have to look at to find out what the problem is? This have been like this for some time now, but I haven't looked into it before, because I don't use TV that muts, but the wife does and when she stats blaming Arch, I have too do something about it.
I have never encountered problem with Arch that i cant solve by using this forum and google
Thanks

Re: [SOLVED]Problem with sound in HDMI

I noticed i got no audio over hdmi on some video file which had a low audio bitrate, i solved it by resampling the sound to 48000 in ~/.mplayer/config :
af=resample=48000

I have a nvidia GT 240.

Re: [SOLVED]Problem with sound in HDMI

No luck with the re-sampling of the sound. One file that i'm having trouble with has a sample rate of 44100 Hz and bitrate of 128 kb/s and resampling it to 48000 didn't work
OK, what else can i look into?

Re: [SOLVED]Problem with sound in HDMI

Ok solved.
I had to tell mplayer what device to us then the files are 44100, so

mplayer filename -ao alsa:device=hw=0.3 -af  resample=48000

works.
Thanks cleanrock  for the input.

Re: [SOLVED]Problem with sound in HDMI

I wonder if resample has any effect in that case, do you get sound without the resample argument for that 44100 file ?

No, i didn't get any sound without resampling .
