Hi,
Sorry to hijack the topic but I believe I'm having the same issue and can add a few more details.
First of all, like Thorsten, I have been reading the threads and trying what's suggested in them with no success.
Let me explain what we're experiencing and what we've tried.
We have 2 users on Mac, both also using the iOS client:
- User #1, on an iMac, using Apple's earbuds, has good audio quality
- User #2, on a Macbook, using generic earbuds with microphone, has poor audio quality (lots of cracks, making it impossible to understand most of the time)
- Both users have perfect quality on the iOS client
- User #2, on the Macbook, without headphones, has reasonable audio quality (there are no cracks or anything like that but of course the volume is lower and there's some echo but I think that's normal because there are no headphones)
Now, because of 1) and 4) we blamed it on the headphones. So, we ordered another pair of Apple earbuds (original) for user #2 that arrived today, but unfortunately the user continues experiencing the same issues.
After these tests, we thought about possible differences between Macbook and iMac, so user #1 got his macbook, configured his extension and had good audio quality. Not sure if this tells us much since the two MacBooks were of different generations, but just adding as much information as possible.
User #2 has tried uninstalling the client, removing all data from Application Support, and reinstalling with no changes.
We've compared audio settings on all macs and they are the same (on the 3cx client and on the system preferences).
We are very keen in getting this fixed so we can help perform any tests necessary to find the cause of the issue.
Thanks!
