Comment(by Quozl):

 An strace of runin-sound shows arecord is failing with:
 {{{
 arecord: pcm_read:1828: read error: Cannot allocate memory
 }}}

 Further up the strace the triggering condition is:
 {{{
 ioctl(4, SNDRV_PCM_IOCTL_READI_FRAMES, 0xbee108fc) = -1 ENOMEM (Cannot
 allocate memory)
 }}}

 File descriptor 4 is /dev/snd/pcmC0D0c.
