![]() ![]() Thanks in anticipation of some help and pointers. Volumio can detect if your DAC has a Hardware Mixer, and enable it. I had enough difficulty making those changes to the mpd.conf file using "vi". Volumio is designed to maximise audio quality - ideally, bit-perfect playback. If anyone thinks of anything about audio settings which they think I may find helpful please chime in, but please go easy on me. Where are the parameters which govern any resampling to be found? Iĭo I need to configure any other settings in my attempt to get bit-perfect playback? Collect some info Check ALSA modules cat /proc/asound/modules 0 sndbcm2835 1 sndusbaudio Check sound hardware cat /proc/asound/cards 0 ALSA : bcm2835 - bcm2835 ALSA bcm2835 ALSA 1 Set : USB-Audio - C-Media USB Headphone Set C-Media USB Headphone Set at b. Will my 16/44.1 or 16/48 files get resampled as they are played back? TL DR (Let's get going already) Reboot and plugin your external USB sound-card, so we start on the same page. You can use ALSA's dmix interface if you want to have multiple things connecting to the ALSA device, but that just resamples to a fixed rate, mixing the sources as the name implies, so I don. ![]() I have noticed that a few 24/192 flac files I have play fine, so I have the following questions :- Apps can connect to the ALSA interface directly, or to PA which in turn connects to the ALSA interface, or to Jack which sits in a similar position to PA. My USB DAC is capable of 32kHz,44.1Hz, and 48kHz at 16 bit only, and most of my music library is 16/44.1 flac files. ![]() Mixer_type "software" # 8 July 2014 Uncommented this line The parts in the mpd.conf file which have been altered from the default settings are shown below.īind_to_address "any" # 8 July 2014 changed from "localhost" to "any"ĭevice "hw:1,0" # optional USB output. I followed the instructions (appropriate to my set up) from this guide :- Bash script for realtime monitoring of a source, mpd, and alsa. > You are now done setting up DeaDBeeF for bit perfect playback. I have mpd (v0.16) working on a raspberry pi running rasbian wheezy OS. In the same Preferences window select > Plugins In the left column select 'Alsa Output Plugin' and then click the 'Configure' button In the configuration window make sure that ALSA resampling is unchecked and that you place a check in box to 'Release device when stopped'. ![]()
