fix microphone lag with PA
Several people have reported to have bag microphone lag with the PA backend. While I cannot reproduce the problem here, it seems that their PA somehow decides to buffer the microphone input for way too long, causing this delay. This patch sets an upper limit to the amount of data PA should hold. This fixes the problem reliably on their side, while having no adverse effects on mine.
