Well................
did it all over again from zero to bot-v5, and still have the "play FAIL sox:" error!?

I believe your system is okay. Check again the owner of the source files. If the owner is still root, change to mpd by chown as I wrote before. My apologies in advance if this does not work.

It should be expected to be like this:

drwxr-xr-x 2 mpd root 4096 May 12 22:08

Also check your /etc/mpd.conf whether or not the /data was defined as music_directory. By defining it, the owner of dirs and files below /data becomes mpd.

twluke: the play command has no connection to mpd, so it neither uses mpd configuration files nor it runs as mpd user. he is executing it as root command, so it should have all access and there is no need to adjust permissions or ownership.

But it matters if mpd is going to be used. Even with the owner mpd, play command by root does work.

That's what I'll do for now........going outside to trim the dead branches off the winter damaged rose hedge and mow the lawn. Wheeeeeeeeeeeee!

apt-get install strace
strace play PATH_TO_ANY_WAV_FILE | grep -v munmap | tail -50

Hi, thanks for this result. I'll try and check this on my Botic5 BBB later tonight.

ichiban · 2015-05-15 1:27 am

I have to say.......

why, even tho /data/remote has my music files mounted, ympd does not show the remote files in the database browser? I suppose it's due to the fact that I mounted the files after bootup and mpd sets up file associations during boot?

Are you kidding, I got out of ympd and tried to umount the music files, & got
umount: /data/remote: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))

,went back into ymp, and lo and behold remote db was there ?????

...and tried playing something, did not work, went back to browse data base in ympd and remote was gone now!!??

ympd (y is a traditional abbreviation of 'another yet') is a GUI interface of mpd and the application actually running is mpd. So, even with ympd, your are going to have a owner problem of the music directory, though miero won't accept this assumption ;-).

Anyway did you try chown -R mpd.root /data/remote/* ? chown -R mpd.audio /data/remote/* may be another try.

tried both and get Permission denied on both ..........

Is it possible to run squeezelite and ympd in the same Bbb but only one working at a given time?

ichiban · 2015-05-15 3:52 am

Shut down and restarted BBB. Got the remote to mount via rc.local on boot up.
So, got a different result it seems, from play.

=====================================================
play /tmp/MUSIC1/Track01.wav
play FAIL formats: can't open output file `default': snd_pcm_open error: Device or resource busy

OK, I reproduced your results with play:

Code:

kramer@beaglebone:~$ play /mnt/music/mp3/Metallica\ -\ Nothing\ Else\ Matters.mp3 

/mnt/music/mp3/Metallica - Nothing Else Matters.mp3:

Done.

This happened when my DAC was not powered up. As soon the DAC gets power:

Code:

kramer@beaglebone:~$ play /mnt/music/mp3/Metallica\ -\ Nothing\ Else\ Matters.mp3 

/mnt/music/mp3/Metallica - Nothing Else Matters.mp3:

I think your issue point to hw issues...
