When I open the settings menu in JRiver I have different options for the output:
FRONT-HW-IEC958-DMIX etcetera. What is the difference and/or which one to choose?
-
I'd recommend choosing a front: or hw: output (which matches your sound card/DAC) with DEV=0.
-
OK, so there is NO difference in quality using either one? Is ALSA the way to go or are there better (more audiophile) solutions?
-
Nope, both front: and hw: are bit-perfect ALSA outputs that bypass (don't go through) any system mixer. If you use the Pulse output, everything is resampled and dithered to 24-bit/48 kHz by the system mixer if I recall correctly.
ALSA is the way to go. If you have both front: and hw: as choices (like I do on Ubuntu), I tend to choose the hw: output for no any specific reason. However on my Arch Linux install I only have front: as an output option so I use that instead. There's no difference in quality and choosing between them is a personal choice. EDIT: I now have the hw: outputs on Arch Linux - thankfully it was easy to do by simply porting alsa.conf and alsa-base.conf from Ubuntu to Arch Linux and the hw: outputs work great along with everything else sound related.

.. on my Arch Linux install ..
can you point me to the location where you downloaded your JRiver Mediacenter that installs successfully on Arch?
-
It's on the AUR. Easiest way to install MC on Arch Linux would be to use a AUR helper for easy installation (I'd recommend Trizen (https://github.com/trizen/trizen)). If you go that route, you will likely need base-devel installed to build Trizen. If you know how to do it manually, you can download the snapshot (or the PKGBUILD) and manually build a MC package for Arch Linux that way. I personally go this route for quick MC updates (I do flag the AUR package out-of-date and blackhole is quick to update the AUR MC package).
https://aur.archlinux.org/packages/jriver-media-center
P.S. There is a "flaw" with the jriver-media-center package on AUR - it'll update each year to the next/latest major MC update. If you don't upgrade every year you might have to manually fork and edit a PKGBUILD to keep a specific older version installed.

Trizen did it for me - thanks!
Now I am looking for an option to play PCM as PCM and DSD as DSD. I selected "no upmixing or downmixing" which works fine for PCM. However DSD is always downsampled to PCM 32-352.
When I select DSD as output encoding everything is upsampled to DSD.
I have a DSD-capable DAC (which plays DSD DoP and native DSD) however, I still need to find the correct setting for JRiver. In MPD, I configured it as follows:
audio_output {
type "alsa"
name "Manhattan"
device "hw:1,0"
auto_resample "no"
auto_format "no"
auto_channels "no"
mixer_type "none"
dop "yes"
replaygain "off"
use_mmap "yes" }
Can you show me the corresponding setup for JRiver?

Enable DSD bitstreaming and don't use any Output Format settings.

.. with bitstreaming - DSD/yes, it works, thanks!
I was searching all the time in the audio output options.
