Difficulties with Mumble

[F6...@wanadoo.fr]

I try to be back on iCW, but I got trouble with Mumble. I'm on W11, with a Play!3 USB sound card. When I configure Mumble with the assistant, it seems to be OK, but when I configure normally via the config menu,or when I connect to a server (US or German) I do not hear any sound.

In the past I was on W10 on another PC, with the same equipment, and all was OK.

I did some other tests today, and it is catastrophic !! Sound level is very very low, latency is very very high.So my set-up is completely unusable to make CW. I have a PicoFrog interface, but it looks like the PC sound card detects the audio very long after the dit or the dah... I did test with the soundblaster sound card, or directly on the PC mic input and results are the same. Is that another "improvement" in Bill Gates products with W11 ???

Bonjour Gerard

Puis-je envoyer votre message à mes amis qui utilisent icw?

Can I send your email to some friends who use iCW?

this audio business on windows can be most frustrating indeed...

  1st thing i would check is windows sound properties, list of sound cards on your playback and recording properties tab...

    does the play3usb sound card have the same sample rate and bitrate    should be 48k sample rate/16 bit(at least for this test)

mumble operates at 48khz sample rate    then check the LEVEL SLIDERs on both    make sure they are turned up all the way(sliders to the right)

then double check and see if your play3usb is the DEFAULT AUDIO DEVICE for both  playback and recording on the sound properties play3 sound card options...

ALSO:

UNcheckmark on your play3usb sound card windows sound properties recording tab,  

 LISTEN TO THIS DEVICE  ===>  that method has WAY too much latency....for monitoring cw sidetones injected into the usb sound card's mic input...

NEXT:

CHECK RECEIVE  on your play3 sound card, 

 1st by going to youtube    pick out a person speaking where you can see their lips moving

 how is the volume level ?  how is the lip sync when watching a LIVE TALK VIDEO   to check for latency issues

   of someone moving their lips talking while visually looking and audibly listening for  LIP SYNC timing accuracy...

if that is good...

then bring up mumble,  take it OFF of    EXCLUSIVE WASAPI MODE and use share wasapi mode(for now) using your play3usb sound card...

have someone you know meet you there in a mumble channel and see if you can hear them(sometimes their volume may not be too loud

compared to what you hear on youtube...so you can adjust your mumble output volume slider(advanced mode settings) to increase it up to 2x...

can you hear them ok now ?

after this is A-OK,    then i will be able to suggest some tests for sending CW into your play3usb for near zero latency sidetone monitoring

while at the same time, sending your cw sidetone into the mumble input...

hope this helps
