With 8 samples/symbol there was aU and CPU at 94% (I have three AMD cores)
I have reduced it to 2 s/s as suggested Cinaed, then aU dissapear and
CPU is at 70%, sound is a little better but still intermittent.
File is sampled at 44100 and with direct connection from wav file source
to audio sink (everything else disabled) it plays fine

Hi Fernando -
Are there are errors / warnings / printouts happening in your GRC log
window or in your terminal? Do you see `aU` getting printed, by chance?
Also, just to be certain, your wavefile was recorded at 44.1kHz and
not at something like 48kHz?
Cheers,
Ben

It works fine when transmitting a cosine, but when I transmit a
audio signal (everything the same) it sounds bad, with noise and
intermittent sound.
What am I doing wrong?
