After some more testing, I think I’ve identified the culprit. First, I’ve taken both AQVOX switches out of the equation and connected like this :
In this configuration :
- Network Bridge disappears [from JRiver]
- Bartók OK
Next configuration :
In this configuration :
- Network Bridge OK
- Bartók OK
Next configuration :
In this configuration :
- Network Bridge OK
- Bartók disappears
Next configuration :
In this configuration :
- Network Bridge OK
- Bartók disappears
Next configuration :
In this configuration :
- Network Bridge disappears
- Bartók OK
So, in the end of the day, it looks like highly probable that D-LINK switches are causing the problem — or, at least, are a significant part of it. I put “switches” in the plural because the AQVOX switches are modified D-Link and this very fact seems to corroborate the diagnosis.
What’s your take on this ?
