If you have any trouble getting sound working, please follow these steps.
They will let you check that audio output and input is working, as well as
avoid common problems.
1. Please listen through headphones when using a microphone. This
prevents feedback that occurs when a microphone picks up the sound
from the speakers.
2. Connect USB/Firewire devices before starting jammr. jammr does not
see devices that are connected after startup.
3. Go to File | Settings (Windows) or jammr | Preferences (Mac) before
joining a jam session and select the input/output devices you wish to use.
In most cases the Audio System, Latency, and Sample Rate settings can
be left at their default values. On Windows the “Windows WDM-KS” and
“WASAPI” audio systems are preferred and work best.
4. Enable “Play back my audio”. If your audio interface has “hardware
monitoring”, “direct monitoring”, “zero-latency monitoring”, or a
similar feature, disabling it is recommended. Although this increases
the latency that you hear slightly, it ensures you hear yourself exactly
the same way that others will hear you.
5. Join a jam session and enable the Metronome button in the
bottom-right corner of the jammr window. You should hear the
metronome click if audio output is working.
6. Play a note on your instrument or say something into the microphone
and you should hear yourself through your headphones. This confirms
that audio input is working.
7. Check that the Send button in the bottom-right corner of the jammr
window is enabled. This button controls whether others can hear you.
Now you should be able to hear others and they should be able to hear
