5 months ago I'm trying to achieve exactly that with a Raspberry Pi 4 and a DAC+DSP. The goal is to incorporate an optical Parametric EQ for room correction and a subwoofer crossover. My hardware setup is based on HifiberryOS 64-bit version 20240115, and the DSP program in use is "DAC+ DSP Universal version 15."
I have successfully implemented a Parametric EQ for room correction over the SPDIF output using the "Sound/Parametric Equalizer/Speaker Equalizer" module, and it works well. However, I encountered an issue where the same module, along with "Sound/Channels," is malfunctioning and incapable of adjusting the analog outputs. Although the features are present, they do not function over the analog outputs.
The "Sound/Parametric Equalizer/Sound Design" module is the only one that can modify the analog outputs, but it operates as a global setting that also impacts the optical output. Therefore, it is not suitable for this specific use case.
Additionally, the Update module is not functional, and I am unable to update to version 20240124 either through the webUI or SSH.

My question relates to the Hifiberry OS DSP function working with the Hifiberry DAC+ DSP Pi Hat. I would like to create a 2.2 setup i.e. 2 speakers and 2 subwoofers. The two speakers would be controlled by the SPDIF out while the two subwoofers would be controlled by the RCA outputs.
Describe the solution you'd like A clear and concise description of what you want to happen.
What I have gathered from the limited documentation is that the system has 4 channels. Can the system by set up in such a way that the audio from Channel 1 with a high pass filter be sent to out with the toslink and Channel 2 with a low pass filter sent out the RCA output. This would be the left channel. Also, the same with Channels 3 and 4. This would be the Right Channel
Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
This would be similar to a product such as MiniDSP HD. 2 channels in 4 channels out with DSP.

I currently own your Digi plus board for Stereo but would like to expand into subwoofers with the DAC+ DSP board. Thank You.
