Thank you John! Agreed on your analysis.
Key is to disconnect from all other audio prior. I was first connected via my cell and volume turned low and was on mute. My phone accidentally came off mute so then I disconnected my phone from webex completely. Prior to disconnecting my cell I was also connected via my primary laptop to be ready to present when my turn came up and my audio on my laptop was via network. I was also On my laptop I could hear everyone but nobody could hear me. I unmuted and muted a few times but could not get the audio to work. So then I connected my phone have had issues with dial back and low volume which was happening so kept clicking from speaker to iPhone since I was coming in very faint. Then I canβt remember what I hit but everyone could hear me but I heard a bad echo on my end which made it difficult to present. Mankamana said everyone else did not hear the bad echo so that was good but sounds like their was still some feedbacks as you mentioned occurring. I would not have had to flip to my cell if my laptop network Audio worked. I presented last week on PIM WG and that went without a hitch. Their is another WG call with LSR tomorrow. I am not presenting but will try to speak up in the discussion to test my pc audio issue. Maybe was some weird anomaly that would have cleared if I disconnected from webex and reconnected. That would have been better then switching to a different audio source. I figured it out my cell and computer both were using network audio so that was caused the echo issue. If I turned off volume on my laptop since rx was working but tx was broke that would have done it. I guess if I had BFD on my pc audio link it would have taken the pc audio down and fixed the issue graceful make before break failover to cell audio.π Kind regards Gyan On Tue, Apr 28, 2020 at 2:16 PM John Scudder <[email protected]> wrote: > Hi Gyan, > > On Apr 28, 2020, at 12:32 PM, Gyan Mishra <[email protected]> wrote: > > Sorry for the audio issues I had during the call.
