Roon server (headless) on NUC5i5RYH running Audiolinux headless.
Roon player on AntipodesEX
Chord 2Qute DAC via usb to AntipodesEX

Description of Issue
I cannot play MP3 or AAC files stored on my SSDs, nor can I stream internet radio station streaming in MP3 or AAC format (I can stream internet radiostations streaming in FLAC format, e.g. NAIM JAZZ radio).
This happens only if I use Roon server under Audiolinux. With th same hardware, but with Roon server running under Windos 10, everything is fine.
Might be a problem with access of Roon server to ffmpeg file under Audiolinux, although command âpacman -Q ffmpegâ returns âffmpeg 2:5.1.2-1â indicating that ffmpeg is installed under Audiolinux
Below is part of log file of Roon server:

Are the codecs installed in the way as described in the documentation?
From your description it seems that you installed ffmpeg with the distroâs package manager, which will put it somewhere in the standard file system. However, Roon expects it in its own directory structure, see the documentation.
Copy it there as described, or you may also be able to link from the Roon directory to the package managerâs version.
To rectify this situation, you will need to make the codecs accessible to Roon OS. This is done by placing the ffmpeg file in the Codecs folder of Roon OSâs shared data directory.
However, with Audiolinux there is no Codecs folder or a Roon OSâs shared data directory. I contacted the developer of Audiolinux about this and he also does not known where the ffmpeg file needs to be placed.
Apologies, I got confused. Indeed: âOn Linux, Roon expects to find the codecs installed as part of the Linux based operating system.â
However:
I am not familiar with Audio Linux, but it doesnât seem to be using Debianâs APT package manager. The Audiolinux website is talking about Arch Linux packages and consequently using pacman commands for installation - like @John_Meerman used as well.
@John_Meerman Where is the ffmpg package placing the files?
Glancing at the roonserver-installer-linuxx64.sh installer script, its comments proclaim that a check for ffmpeg is performed on installation, but I canât see it being done. Maybe I am missing something, but:
#
# Check for proper architecture
#
case "$MACHINE_ARCH" in
armv7*)
if [ x$ARCH = xarmv7hf ]; then OK=1; fi
;;
aarch64*)
if [ x$ARCH = xarmv8 ]; then OK=1; fi
if [ x$ARCH = xarmv7hf ]; then OK=1; fi
;;
x86_64*)
if [ x$ARCH = xx64 ]; then OK=1; fi
;;
i686*)
if [ x$ARCH = xx86 ]; then OK=1; fi
;;
esac
#
# Check for root privileges
#
if [ x$UID != x0 ]; then
echo ""
echo -e "${COL_RED}${COL_BLOLD}Error:${COL_RESET} This installer must be run with root privileges. Exiting."
echo ""
exit 2
fi
#
# Check for ffmpeg/avconv
#
if [ x$OK != x1 ]; then
echo ""
echo -e "${COL_RED}${COL_BLOLD}Error:${COL_RESET} This package is intended for $ARCH platforms. It is not compatible with your machine. Exiting."
echo ""
exit 3
fi
The code following the ffmpeg check comment is actually the output for the previous architecture check
ffmpeg is in /usr/bin and in /usr/share
However, when i issue command â/usr/bin/ffmpeg -hâ I get no help but an error message: error while loading shared libraries: libsrt.so.1.4 : cannot open shared object file : no such file or directory
However, when I issue e.g. command: â/usr/bin/fdisk -hâ I do get help information.
And I am confused by Audiolinux. On one hand they use pacman, but on the homepage they also say that they have a new package manager, âyayâ. And here on another forum (recommended by Audiolinux) they install ffmpeg with
For ffmpeg, go to console and check if it is already installed:
yay -Q ffmpeg
If not, you can install it with
yay -Sy ffmpeg --noconfirm
Maybe libsrt is simply not installed? ffmpeg depends on it. I understand that pacman should resolve dependencies automatically, but who knows with this Audiolinux contraption
excecuting âyay -Q ffmpegâ returns "ffmpeg 2:5.0.1-1,therefore it seems to be installed
However, excecuting âyay -Q libsrtâ returns âpackage âlibsrtâ was not foundâ
Also âyay -Q libsrt.so.1.4â yields âpackage was not foundâ. (I donât know exactly the spelling of the name of libsrt package, Iâam illiterate in Linux)
This is the correct check. OK, so it is installed (as it should be because ffmpeg depends on it and the automatic dependency resolution of the package manage is supposed to autoinstall it when you install ffmpeg).
However, your srt version is version 1.5.1 and your ffmpeg is looking for version 1.4, hence the âerror while loading shared libraries: libsrt.so.1.4 : cannot open shared object file : no such file or directoryâ
This looks very much like an error in packaging to me. However, one would think that other people would have noticed.
Please list the dependencies of ffmpeg, using this command:
$ pactree ffmpeg
Note: You may have to install packman-contrib first. (See pacman - ArchWiki)
To test if ffmpeg works at all (I expect that it will not), you can take a flac file and try to convert it to an mp3:
ffmpeg -i your_file.flac -ab 320k your_file.mp3
This should create a 320 kbps mp3 file in the same directory as the flac file is. The flac file will not be changed.
I figured Audiolinux is not the ideal first distribution to use, but then I used Slackware as my first distribution in 1993 or so, and I survived. The path may be steeper but you will learn with each step.
(I wonât be asking what your expectation is that Audiolinux is improving in an ethernet-connected machine.)
Nope, ffmpeg does not transcode a flac file,I get the same error as before:
âerror while loading shared libraries: libsrt.so.1.4 : cannot open shared object file : no such file or directoryâ
So,it seems that an older version of srt needs to be installed?
(I have a 2nd NUC5i5 with Roon server running under Windos 10, if youâre in the neighbourhood I can play you some music to you via my AntipodesEX/2Qute from Roon on Audiolinux vs Roon on Windows 10, and even from Roon serving internally on the AntippodesEX, and you can decide if you hear any differences, and if so, which setup you prefer. I wonât disclose my preference yet because I donât want to introduce any bias in your test)
It looks to me like an error in the dependencies of the package. The person creating the ffmpeg package should know which srt version it needs, and it should be pulled in automatically when installing ffmpeg.
It is possible that there is an srt-1.4* in the package repositories that you can install explicitly, but it depends on the Audiolinux maintainers.
However, in any case this looks very much like an Audiolinux error to me, if ffmpeg fails with the transcode command, not a Roon error.
Not going there Itâs irrelevant to the issue at hand, anyway. Except that a more mainstream distribution would be easier to understand with this error.
