alsa-project/alsa-utils issue #179 was edited from chconnor:
Hello: I issue a command like this:
`arecord -t wav -c 1 -f S16_LE -r44100 -D hw:2,0 test.wav
`
It works fine, but then I hit ctrl-C to terminate. This works, but the file has "junk" at the end that repeats the last fraction of a second. E.g. in this demo file I ctrl-C when I say the word "one", and the recording is like "three, two, on-on":
https://caseyconnor.org/pub/audio/arecord_bug.wav
It's as if it is mistakenly writing a buffer an extra time?
(In my total ignorance and total lack of qualifications, I traced the code to [here](https://github.com/alsa-project/alsa-lib/blob/d28e8cb29485cc93f741b01dc65893c798359963/src/pcm/pcm.c#L7544), but I get lost and can't see if anything is awry...)
