> Output file called "mgps.wav" seems to be good. It plays without any comments in any player that I have. But I get strange "Cache not filling!" every few seconds after running mplayer. I tried to use "-cache" with variable values (from 100 to 10000) instead of "-nocache" but nothing changes.

If there's no problem you don't have to worry.
The message is mostly for debug purposes, e.g. if the cache process crashed.
It only means that MPlayer is waiting a long time (> 100 ms) for more data to come in.
If you get it a lot it might cause things like A-V sync, unnecessarily high
CPU usage and things like that, but as said unless you see an actual issue
you don't have to worry about it.
I can't see why/how that message could appear with -nocache though...
