Irit Katriel  added the comment:

ossaudiodev is deprecated as per PEP 594, so there won't be further 
enhancements to it.

[issue22094] oss_audio_device.write(data) produces short writes

Alex Shkop added the comment:

It seems to me that OSS device doesn't accept more than SNDCTL_DSP_GETOSPACE. 
Looks like this depends on OSS version because OSS docs state that since 4.x 
one shouldn't use SNDCTL_DSP_GETOSPACE at all 
[http://manuals.opensound.com/developer/SNDCTL_DSP_GETOSPACE.html].

I have OSS 3.8.2 and I can reproduce the bug. Can someone with OSS = 4.0 
confirm that dsp.write() works as expected?

From Modules/ossaudiodev.c:

/* NB. writeall() is only useful in non-blocking mode: according to
   Guenter Geiger gei...@xdv.org on the linux-audio-dev list
   (http://eca.cx/lad/2002/11/0380.html), OSS guarantees that
   write() in blocking mode consumes the whole buffer.  In blocking
   mode, the behaviour of write() and writeall() from Python is
   indistinguishable. */
