PCM.exe crash when answering softphone call

shayne · 02-08-2010, 05:37 PM

I have a user that when going into softphone mode on the call manager will crash when a call is connected.

User is on call manager 9.2
Windows 7 pro (x86)
TAPI is setup correctly
we have other Windows 7 users that do not have this problem at all.
I have another laptop with the same configuration (windows 7, etc...) and when I log into his account on the call manager I don't have this issue at all.

the error says:
EyeP Stream
Unexpected Failure
Program PCM.exe
Version EMStream W32 5.7.20 SH
File: EMWasapiBase.cpp
Line: 445

I've uninstalled and re-installed plus blown out any remains in the registry. I'm all but formatting the machine and starting over, unless anyone has any ideas thanks...

Before you format the machine try unistalling any antivirus programs. Seen this once before and just disabling the firewall/antivirus didn't help, but uninstalling it did.

I resolved my issue by making sure that i had the latest audio driver. I installed the driver, rebooted and bam! Problem Solved.

Having this issue too -

version 9.2 build 14.41.4603
Windows 7 Enterprise 32bit
Dell Optiplex 960

Tried updating the audio drivers to the latest version according to Dell's website and no luck - same error. Softphone seems to work though, the error pops up upon placing or receiving a phone call.

Ok, it seems that the error only appears when I am using a non-USB headset (just plugging headphone/mic into the audio jacks on the front of my tower). USB headset works perfectly.

I too can verify this issue with PCM installed on Windows 7 (mine happens to be on a Dell machine as well). The issue only occurs when using the onboard audio device. A USB headset (Logitech, in our case) bypasses the issue.

I get the same error when my laptop is docked, but out of the docking station, it works just fine. Any suggestions?

I had several problems running on W7. I am on release 10.1. At the en I selected the "compatibility mode" option and set to Windows XP. No big issues now. waiting to release 11.1 to upgrade.
