Latest Build broke ALSA sound (play works - aplay screaches)

All,

  I just installed all of the packages from the 2/8 - 2/10 build. The initial
display of khelpcenter worked fine, but I noticed that I had no sound. After
fighting with sound in the first set of packages, I was surprised that sound
would just quit working in the latest set.

  I then opened konsole and tried:

21:52 valhalla:~> aplay /opt/trinity/share/sounds/KDE_Startup_1.ogg
Playing raw data '/opt/trinity/share/sounds/KDE_Startup_1.ogg' : Unsigned 8 bit,
Rate 8000 Hz, Mono

  I got a horrible screaching sound from speakers. I then tried:

21:52 valhalla:~> play /opt/trinity/share/sounds/KDE_Startup_1.ogg

/opt/trinity/share/sounds/KDE_Startup_1.ogg:

 File Size: 124k      Bit Rate: 125k
  Encoding: Vorbis
  Channels: 2 @ 16-bit
Samplerate: 44100Hz
Replaygain: off
  Duration: 00:00:07.95

In:100%  00:00:07.95 [00:00:00.00] Out:382k  [      |      ] Hd:0.1 Clip:4
play WARN rate: rate clipped 2 samples; decrease volume?
play WARN dither: dither clipped 2 samples; decrease volume?
Done.

  It sounded great. So checking, play is provided by sox 14.4.1-4. That begs the
question, Why does play work fine but aplay fail?

  Suggestions?
