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

regards

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?
