Dsp to dlna
I've been playing with a SOTM SMS-100. I tried unsuccessfully to use DIRAC on my server and output via DLNA to the SOTM unit.
For those that aren't familiar with DIRAC: DIRAC applies the DSP filter at the output. Typical setup is JRiver--->DIRAC WASAPI---->ASIO or kernel DAC device.
With SMS-100 DLNA as the endpoint, I select JRiver ASIO for the DIRAC output, as DIRAC lacks DLNA. When the SMS-100 is configured, it automatically creates a DLNA zone in JRiver which is the default zone assigned to the DLNA device. This cannot be changed.
I can set up 2 JRiver instances and loopback through one of the instances using JRiver ASIO driver. I can easily select JRiver ASIO as the output for DIRAC and the signal loopsback into the first instance of JRiver. However, for some reason, the JRiver ASIO driver will not work when looped back into the DLNA zone JRiver instance. I also tried linking another zone to the DLNA zone and that doesn't work either.
Unless DIRAC updates their software to enable DLNA or JRiver updates their software to allow JRiver ASIO loopback through a DLNA zone, the SMS-100 isn't going to work with DIRAC.
I think this is a limitation within JRiver. JRiver won't allow the ASIO loopback only into a DLNA zone. I also noticed that convolution and all other DSP is disabled inside the DLNA zone.
It would be great if JRiver (or DIRAC) could address these issues, as I believe there are many folks who want to stream to a DLNA device and use DSP in the process. DLNA seems like a very promising advance in CA. I just hope that it brings some of the more advanced features of CA along with it.
