I'm using 0.9.15-test3 with various applications including rhythmbox and I am noticing the audio will be distorted and clipping at times, although the overall output volume is quite reasonable (I'm 40, not 15). Looking in the volume control I have RB set (in the Playback tab) at 49% volume and the actual sound card (in Output Devices) at 49% also. These seem like reasonable values that should not cause the louder sequences in various tracks to distort or clip. They certainly didn't with the 0.9.10 that I am upgrading from. Oh crap. Having the volume control open just triggered: E: core.h: Assertion 'pa_object_refcnt(pa_object_cast(o)) > 0' failed at ./pulsecore/core.h:159, function pa_core_assert_ref(). Aborting. again. ~sigh~ b.
