I have device "Bus 001 Device 004: ID 0cf3:3004 Qualcomm Atheros
Communications AR3012 Bluetooth 4.0" and "Sony MDR-ZX770BN" headset.
It return mtu=183. This patch crash pulse on assert sink.c:1380
"pa_assert(pa_frame_aligned(length, &s->sample_spec));"

I check mtu 180/182 (manual hardcoded for aligment) - pulse work, but
HSF/HSP profile not have sound.

A2DP work wine with big mtu.
