aplay broken in xo 1.75

[godiard]

The activity Distance use the binaries aplay and arecord in the package alsa-utils to play a sound in two xos and record the result and calculate the distance. The last version in ASLO [1] is working in os3, but in os41, can't play the test sound the commands used are:

/usr/bin/aplay fname

/usr/bin/arecord --file-type=raw --channels=1 --format=S16_LE --rate=48000 --duration=10  fname

I know record is not working in xo-1.75 but play should be working.

The test sound file can be downloaded from [2]

In a xo-1.75 if in the command line I do:

[olpc@localhost ~]$ /usr/bin/aplay ]outtqh4Xr
]outtqh4Xr: No such file or directory
[olpc@localhost ~]$ /usr/bin/aplay outtqh4Xr

Attached is the file used to test aplay

No action required until kernel audio driver is feature complete, then please retest.

Aplay seems to work in 11.3.1 os20, although the test file attached to this ticket is prone to causing the audio channel swap issue fixed by #11411 for later-made recordings.
