Sound Probs with R4B #99

Closed Mickinator closed 3 years ago

Mickinator commented 3 years ago

Hi everybody, hi Kevin,

first let me say Jambox does real good job. Wonderful work, thank you.

I' m very new to Jamulus, so I have no experiance. I started with a raspi 3B and Jambox and it made a good job. But I wanted to reduce the latency, and so I changed to Raspi 4B with 4 GB.

It works too, but now I have a distortion if I' m playin piano. (no red LED). I think it would be better to increase the buffer size. I ve read I can do that by editing the jack configuration. And here is my problem: I do not know to find it.

Who can help ?

Ok, i ve found /etc/jackdrc.conf to edit the buffersize for period and nperiods. But i have no good results. 64/8 works best, but there are crackles in the background. if I use 128/4 (like I use with R3) the result is more worse than before and not so good as using the R3. What can I do?
