Hi @moos ---- Thank you for touching base with me and providing the requested feedback. Both are very appreciated and my apologies for the wait.
From your most recent post
“Tonight I tried to assign a fixed DHCP address to the MacBook Pro and I listened for a couple of hours without problems. I’m more and more convinced MacBook Pro is a bottleneck both for its WiFi performances and its processor (who needs to use Dirac Live). What is your experience here?”
In my home use, I actually use the similar model of MacBook pro on occasion as an end point, but the only difference between our setups is that I am using a hardwired connection (via ethernet) from my router to the unit. In my most humble opinion these are the variables that I would consider looking into:
Start here:
1a) What is the experience like if you mount the iFi iDAC2 to the MacBook Pro instead of the Yggdrasil DAC?
1b) Try swapping out the USB cable between your MacBook Pro and the DAC.
- You’ve mentioned a few times that playback via the internal speakers on the Macbook Pro had no issues, which would indicate to me that your music is making it to the device successfully. However as soon as it is passed down the line to your DAC, that’s when you receive the dropouts. So the first two suggestions (“1a & 1b”) is where I would start.
Troubleshooting continued:
2) When you are noticing these dropouts, are there other active applications running on the Macbook pro? If there are, what happens if you quit all other process and just let RoonBridge run?
-
Try reinstalling RoonBridge on the MacBook pro if you have not done so already.
-
The most conclusive test would be to try with a hardwired connection between your Apple router and the Macbook Pro, but being as you mentioned that the location of your devices would not allow you to do so, I would consider also testing with a different (non-apple) router if possible. As mentioned by @philr we have indeed seen a few issues with these devices.
