AuviTran Network ASIO Streamer 11
5 TROUBLESHOOTING
Although we have made every effort to make sure that the AuviTran Network ASIO Streamer will work well on a wide range
of PC hosts and network architectures you may still encounter configuration problems that will affect audio record or
playback. This section will help you troubleshoot these problems.
5.1 The ASIO Control Panel does not detect the device
Make sure no other PC on the network is using the device. A device can only be used by a single PC at any one
time: the other PCs on the network will not be able to detect the device, let alone use it, until that first PC has
stopped streaming.
Use AVS-ESMonitor to review the configuration of the device, make sure the device‟s Control tab shows that the
ASIO feature is active.
If you are targeting an AVY16-ES100 then check that the 3
rd
port mode is „3
rd
port+ASIO‟.
If you are targeting an AVM500-ES or an AVM500ES/3ports then make sure that the „ASIO Mode ON‟ control is
checked on the right port of the device.
If the ASIO status is not visible then maybe your device does not support this feature or needs an updated firmware
(please see Supported audio devices).
Make sure the PC is connected to the right port of the device.
If you are using an AVY16-ES100 then there must be a connection between its 3
rd
port and the PC.
If you are using an AVM500-ES/3port then the connection must be between the Port C and the PC.
If you are using an AVM500-ES then the connection must be between the Port C, Port D or Port E, whichever you
enabled the ASIO feature on, and the PC.
If the Control Panel still can‟t detect the device then maybe the network cable is faulty, try another one. If you are
connected through a switch then try another port.
5.2 There is no sound at all
That‟s when the device is detected, the ASIO application is playing, the channel meters are moving, but you still can‟t hear
anything.
In the ASIO control panel make sure that the right device is detected and selected. Also make sure that the
configuration has been saved (the „Apply‟ button should then be disabled).
In your ASIO application, please verify that the AuviTran ASIO driver is actually selected and that its input/output
channels are actually connected to the application‟s own channels.
In AVS-ESMonitor check that the ASIO feature is enabled on the device. Also check that the ASIO channels are
correctly patched and that the output device is actually present.
5.3 Sound quality is poor
The AuviTran Network ASIO Streamer cannot rely on proprietary hardware to produce predictable performance and is highly
dependant on the host PC performance and health. When sound quality is not optimal (sound pops, clicks or other glitches
occur) then most probably either the PC or the network performance is to blame.
Use a reasonably fast machine. We recommend that it has at least a dual-core CPU, at least 2 GHz clock speed,
lots of RAM (that‟s more than 1 GB for Windows XP and more than 2 GB for either Windows Vista and Seven) and
a fast and large hard disk.
Make sure all the system resources are available to the ASIO application: close any unneeded application and
service when streaming, make sure your machine is free from viruses. You can also set the ASIO application‟s
priority to high (in Windows Task Manager).
Use a fast Gigabit Ethernet adapter and make sure that it has the latest drivers available from its manufacturer as
this can dramatically improve the performances, especially with Windows Vista and Seven.
Use a dedicated network adapter card for streaming. AVS-ESMonitor should optimally be using another network
interface. If that is not feasible, or if your PC has only one interface, you should try and disable the EtherSound
service while streaming. This will prevent you from controlling the EtherSound network and device from this PC but
it will ensure that all the network bandwidth goes to the streaming.
In the AuviTran ASIO control panel try and select a greater ASIO buffer size. This will increase the audio latency
and relieve some of the host CPU stress.
If all else fails, and if you don‟t absolutely need to record all the channels then you can use a lower I/O count for the
device (that‟s in the control panel, in the „Network Audio Device‟ section). This will decrease the required network
bandwidth.
