As a data point, an attempt to record 10 seconds through alsa will hang 
indefinitely, and leave an empty file stub:

%  arecord -v -N -f cd -t wav recording.wav
Recording WAVE 'recording.wav' : Signed 16 bit Little Endian, Rate

% file recording.wav 
recording.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 
bit, stereo 44100 Hz

So, while playing audio that way works, it looks like recording through 
the alsa oss plugin is plain broken.

Cheerio,
