I have some users with a strange problem, this do not apply to all my users. This is the problem reported from the local admin:
Symptoms:
When a user is called internally or by an external party, the call volume will sometimes start off quiet, and may continue to be quiet for the whole call or may jump in volume suddenly during the call.
Cause:
I have not determined the cause, and It is not re-creatable at will, but I have experienced it myself on several occasions. The users affected are using Lync certified headsets or handsets, it happens on both. By troubleshooting I am fairly certain this is
software related and its either Lync or the interaction between Lync and the Windows sound mixer/drivers.
Resolution:
I cannot resolve this issue, but have discovered a temporary work around. When receiving a call that is quiet in volume if you open Lync and click on the settings icon, the volume jumps up to normal levels at this point, usually you only have to do this once
and calls during the rest of the day are ok, but you have to do this every day.
Conclusion:
I cannot be certain if this is a Polycomm driver issue, a Microsoft driver or software issue or something else but users have complained about it on and off since they migrated to Lync EV.
Anyone having ideas on this one?
