The int cast is wrong and unnecessary as internal->buffer_time is a pa_usec_t (which is uint64_t). It does not even make sense to cast it to a uint as it being multiplied by the sample rate (and then divided by 1000000 before it get fitted into battr.tlength, which is a uint32_t). Also ditch the "+7" trick for format->bits as the function would have returned already if it isn't 8/16(/24).
We really just want to set battr.tlength (as its default is 2s). It's better to left the others for pulse to determine.

Wouldn't this make more sense as unsigned?

@ePirat To be frank, my C is really bad, so I don't exactly know. I don't even remember why I made this change because this was so long ago. I think the reason was that atoi returns int, and/or there was this (int) casting for (internal->buffer_time * format->rate), so to prevent something goes wrong accidentally (like it being an unsigned resulting in other variables getting set to some unexpected value), I went with int.

Ah, actually it might be because atoi(value) * 1000 was apparently due to buffer_time being a "usec", and because there is no "pa_msec_t", I went with what atoi returns when I remove the * 1000 (and didn't care what tlength is)...

Should I maybe just ditch this line of change? Like keeping it as pa_usec_t (uint64_t)? Or should I change it to unsigned int (or uint32_t?) anyway?
(Does using 64-bit for it minimize the chance of overflow as of internal->buffer_time * format->rate (i.e. before / 1000)? Or does the "limit" come from what tlength is instead?)
