Problem with SND_PCM_MODE_STREAM under 6.1

After installing QNX RTP 6.1 I’m having a problem with some code which worked fine under 6.0. When using stream mode, snd_pcm_plugin_write fails and returns -ENOTSUP which isn’t even listed as a possible return value. The same code modified to use block mode works just fine.

The code in question can be found at:

Thanks in advance.
