Can't get HQPlayer to work

You don’t need the NAA running on your computer if you are connecting your DAC to the computer by USB. The NAA program is intended to be run on a network device, not the computer on which HQP is running. For example, you might run the NAA program on a Raspberry Pi which has an Ethernet input and a USB output to your DAC.

Stuttering can occur when the settings in HQPlayer exceed the computational power of your computer. You can either reduce the settings or use a more powerful computer. If your computer has an Nvidia graphics card you can also enable CUDA (use the greyed option) which offloads some of the processing to the graphics card.

What are the specs of the computer running HQPlayer ?

In the screenshots above the default output is set to source, which means that a PCM input will result in a PCM output and similarly for SDM (DSD). It is more usual to explicitly select PCM or DSD output. Upsampling to DSD is more computationally intensive than PCM.

You also have different filters selected for 1x and Nx which may or may not be intended. The 1x filters are used for 44.1 or 48 kHz source files and the Nx for 88.1 or 96 kHz and higher source files.

What upsampling rate are you using ? You usually want to send your DAC the highest sampling rate it can take as an input. In the case of the Chord Hugo 2 that is 768 kHz PCM or DSD 512 (use the 44.1 multiples unless you know the Hugo 2 has a 48 kHz DSD oscillator). It may be that those settings are too demanding for your computer, in which case you might reduce the maximum upsampling bit rate.

The choice of modulator and filter can also affect the computational intensity. In the DSD settings you have poly-sinc-xtr-lp-2s selected for 1x which is a relatively long filter. Depending on your computer power you might need to reduce the sampling rate to DSD 256 or 128 to use that filter.

Thanks, all sorted now. PCM at 768,

Linux novice here. Can someone help show me how to mount a NAS for use with HQPe? Thanks.

If you use HQPlayer OS, then you have a link at the bottom of the web interface where you can mount SMB share from a NAS. Should be relatively straightforward. It will be at /smb and you can scan that for the library.

Please be a little more explicit. I tried many types of paths in Share and it said “Success”. Now in the web interface Library Path I’ve tried different things as well and can’t find it.

For example “//someserver/someshare” and then username and password.
