Troubleshooting
For the most frequently asked questions refer to faq.2n.cz.
2N® Net Audio Decoder or 2N® Net Speaker is not displayed in the Destinations & Zones menu
Make sure that that DHCP is enabled for your network, or you must know the IP address, subnet mask and gateway which can be assigned to 2N® Net Audio Decoder or 2N® Net Speaker. When the other LAN devices receive the IP address automatically, 2N® Net Audio Decoder or 2N® Net Speaker may not get it due to restrictions set by the IT department. This setting then automatically assigns IP addresses only to the known/registered LAN devices based on their MAC addresses.
Firewall may also block the 2N® Net Speaker connection
When 2N® Net Audio Decoder or 2N® Net Speaker disconnects and then tries to reconnect to the same port, the active firewall may not permit such connection.
2N IP Audio System sound is jerky
You can set the Sound path delay for 2N® Net Audio Decoder or 2N® Net Speaker and all intercommunicating components on the Destinations & Zones tab. The default value is 40 ms, which is typically sufficient for local area networks (LAN), or you can increase the value to up to the maximum of 10,000 ms. You can also set the Sound path delay for the other system applications: 2N® IP Audio Console or 2N® Virtual Sound Card in the respective application settings.
