I am using Windows 10 on an MSI PE70 6QD laptop, with a Realtek High Definition Audio sound card. I use both Skype and Skype for Business 2016 (part of Office 365). I can make and receive calls using Skype without any issues, using my in-ear headphones or without them.
When I try to join Skype for Business 2016 calls, I cannot hear anyone and I have never been able to do so. The other party can hear me clearly. I have tried to make calls both with headphones and with my normal PC speakers. The issue always remains the same. I am sure that my PC speakers and my headphones are working fine.
Under my sound devices, on the Playback tab, I see two devices registered: Speakers, and Realtek Digital Output. Under Speakers I see Realtek High Definition Audio, and Speakers are selected by default. Under Realtek Digital Output I also see Realtek High Definition Audio, but it shows as not connected.
In Skype for Business 2016, under Tools / Options / Audio Device, I see "Other Device - Realtek High Definition Audio" selected as the device I want to use for audio calls.
I have updated my audio drivers and Windows reports that the driver on my PC is the latest driver. I have also followed these instructions, to test the quality of the incoming sound is okay in my headset: https://support.office.com/en-us/article/Set-up-an-audio-device-for-Skype-for-Business-2533d929-9814-4349-8ae4-fca29246e2ff
My Skype for Business 2016 build version is 16.0.6925.1049 and I installed the 64-bit version of Office 365. My Windows is configured to automatically update itself whenever it needs to.
Please help! This is making my office life ****!
