Hello all and a belated Happy New Year,
I'm posting this here since I'm not sure if this is a hardware or software problem.
I've run into a peculiar problem with using Bluetooth.
This is on a friend's computer that I'm in contact with.
Bluetooth dongle is Asus BT211 with Athero drivers
Headset (earpiece) is Plantronics M20
This happens on XP as well as on Win 7-32b.
Symptoms: When using VOIP, the audio in the ear piece is delayed,
so my friend hears speech as if the other party , me or another friend,
is speaking very slowly, at about half speed.
In addition the audio (voice) is modulated, having like a tremolo- or vibrato-like effect.
But here's the riddle:
PC sound, music or spoken word, to BT ear piece (via the USB BT dongle)
is fine and very clear and range is good ,about 30' or a little more.
Microphone is clear to PC and also to other party.
VOIP to PC wired headset is clear both ways.- send or receive.
VOIP is also clear via computer speakers.
* But using VOIP via BT causes the audio distortion in the BT earphone.
In addition a "walky-talky " effect takes place as well,
I.o.w. only 1 person can talk at one time, interruptions will not be heard.
From that I might conclude that BT is not duplex audio?
Has anybody come across this and what is the cause or the solution to this?
To reiterate:
PC audio to speakers - ok
PC audio to wired headset - ok
PC audio via USB BT dongle to BT headset(ear piece) - ok
VOIP audio to speakers - ok
VOIP audio to wired headset - ok
VOIP audio via USB BT dongle to BT headset - distorted.
So where's the hang-up ? Could the BT drivers be at fault?
Thanks for any ideas to solve this annoying problem.
Peter E.
