This attenuates the PCM audio in software - it changes the bitstream for PCM and, more importantly, BREAKS DSD. Software volume: as soon as the volume is anything other than 100% (loudest) on the player Plex turns on the volume filter. Plex turns on filters at the client for various reasons - the main two are: I did see transcoding when playing a DSD file (.dff I think) which is why you need DSD in FLAC. Transcoding shouldn’t be happening in a local network with FLAC audio but just in case verify that by looking at the server’s dashboard when playing a track. The key point to getting decent high-def out of a Pi is preventing transcoding at the server, and filtering/resampling at the client. See post above for sticking DSD into FLAC. I didn’t test this as my setup is stereo, and I’m not sure if the E30 can decode it anyway).Īll of my high-def music is either PCM or DSD, stored in FLAC containers (aka, DSD over PCM, or DoP). If you’re only doing this for music, don’t bother with passthrough (unless you have some DTS audio, I guess. You also get a ton of other devices to ignore (E30 front speakers, E30 stereo, E30 4.0, E30 4.1, …). Firstly it’s USB (not coax or fibre) and secondly the supported bitrates of the device by far exceed those of S/PDIF. The short of it is if you want high-def audio you must choose the S/PDIF device (also known as iec958). Plex on a Pi presents the DAC in a strange way, quite unlike on a Mac for example. Sure you could spend AUD500 on a linear DC supply for the DAC but read Do you need a linear power supply… first.Īnyway the good news was that the Pi saw the connected DAC without any issues no drivers or kernel tweaking necessary. I recommend using a decent (Apple or other big brand) USB switching power supplies for both the DAC and the Pi ( USB chargers tested). That plus a trusted reviewer ( Review) could barely tell the difference. I decided against the D50S due to price (I wasn’t sure it would work) and I didn’t need the bluetooth audio feature. I purchased a Topping E30 USB DAC for AUD200 after some investigation. My Raspberry Pi 3 B v1.2 is the client (player) in this scenario, on which I tried various incarnations of Plex. It is intended to be a partial success story for anyone wishing to achieve the same. The default username is root and the password is plex.This post is a follow-up to cong314159’s post that got me interested in playing high definition audio to a DAC. Now that you have the IP of the Pi, SSH into it. I can not explain this for every router make and model, so i assume you are able to figure this out. The Plex interface does not show this so you will have to scan your network or find it by going into your router and checking for the connected devices. Start off by finding the IP address of the Pi. There are a lot of timezones available on the image, it just requires some adjustments to permanently use them. After flashing a new image, i keep forgetting how to change the timezone. On a regular basis there are new images published for the nightly Plex Media Player for embedded systems. Besides flashing the image to an SD card it requires no setup.Ī default timezone is configured but the interface provides no (easy) way to change this. Plex Media Player (or PMP) for Raspberry Pi is an easy and light weight way to get Plex Media Player running on a Pi.
