PRSPS Posted October 10, 2019 Share Posted October 10, 2019 System was working fine for months; today received automatic upgrade to WINDOWS 10 version 1903, now the outgoing message plays to monitor speakers not to the modem and out to caller's telephone. Settings - AUDIO - Call Announcement is set to default Playback Device, only other choices are monitor or headphones. Link to comment Share on other sites More sharing options...
Fluke Posted November 3, 2019 Share Posted November 3, 2019 I had the exact same issue. I had to go back to the previous version of WINDOWS 10. I didn't spend much time trying to figure out what was wrong. Link to comment Share on other sites More sharing options...
Fluke Posted November 17, 2019 Share Posted November 17, 2019 I found this fix online, applied it exactly, and it worked. It involves editing the Win 10 registry. I am using a US Robotics 5637 USB voice modem. These instructions are for a 64-bit installation of Win 10. If you are using a 32-bit version, you only need to do steps 1 and 3. Load REGEDIT, then: 1) Goto [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32] Find the last wave… parameter, for example, if "wave" and "wave1" exist, then create 1 new entry wave(+1): "wave2"="serwvdrv.dll" 2) Goto [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32] Add the same as in (1) "wave2"="serwvdrv.dll" 3) Restart the computer.
