To reduce load on the SMS-200, run DSD in native mode, DoP takes more cycles and the little Dual core Allwinner ARM on the SMS-200 is already quite close its limits running is a lot less resource intensive and I can get SMS-200 to handle DSD512. This is almost identical to the NUC setup I am using for the NAA, my USB image contains the NAA software instead of HQP server.
HQPLAYER WINDOWS INSTALL
No need to install your own version of linux or mess around with the linux distributions. There is a version of HQ player embedded that comes in a bootable USB disk image, it is a custom barebones linux kernel with HQ Player server already built in. Get a microATX or mini ITX motherboard, 4-8Gb of memory, no disk, boot from a USB 3.1 stick using the image below. Not sure what your budget is on this one but if you have 300-400 USD to spend on the CPU take a look at the Ryzen 3700x from AMD, 3.6GHz 8 cores. I tried to add firewall permissions, run without antivirus but with not success. No matter what I do I the HQPlayer cannot see the NAA. I am running the networkauodiod.exe on the NAA PC and try to connect from the other PC. Linux can consume much less resources if you do not have the GUI, with Windows there is no option and W10 has a lot of baggage. I am trying to setup HQPlayer on windows 10 with another windows 10 as NAA.
HQPLAYER WINDOWS FULL
You would really need a quadcore or better running at 3.5GHz+ to get the full benefit of the highend DSD modulator and filters. The 4650U is a dual core clocked at 1.7GHz, it did quite well giving you DSD256. * hence all hardware that is known to support this format has to be * don't have a designated bit field to denote DSD-capable interfaces, * augment the PCM format bit-field for DSD types. * snd_usb_interface_dsd_format_quirks() is called from format.c to Here is part of the kernel source documentation The current list of supported devices can be found here Linux does not support DSD Native mode for the U16 only UAC 2.0 mode There is no registration for the U16 or the ES8620 chip from ESS. On Linux, DSD512 native support has to be registered with the linux kernel in order for HQPlayer's NAA Image to support DSD512ĪRM Linux kernels on Sotm SMS-200 and Sonore uRendu have to be on 4.9x or newer to work with DSD512
HQPLAYER WINDOWS DRIVERS
On the Mac ASIO drivers are required for DSD512, Exasound is the only manufacturer I know of. Mac and Linux support USB 2.0 UAC audio mode without drivers but it gives you DSD256 via DOP and PCM. Nvidia GPU can offload the filter work if you have one installed in the PC.
Let HQPlayer do the PCM->SDM conversion, otherwise the ES9038 does that, I find it does a poorer job. PC have at least a Quad core CPU with 4 real 3.5GHz, the clockspeed can be lower if have more processing cores. SD Modulator: DSD7 or ASDM7 (can cause noise pumping on noisy tracks)įilter: polysinc-xtr-mp or polysinc-ext2 if your PC is really weak. The newer EC modulators cannot yet be used at DSD512 with the current avaiilable CPUs. However SMS-200's implementation of the NAA is limited to DSD256, this has nothing to do with the Amanero.ĭSD512 dropouts are a symptom of inadequate CPU processing capabilty on the PC. Yes, Amanero works with DSD512 if Firmware_2006BE10/CPLD_1081_SWAPPEDDSD is used.
