The error in pulseaudio is from a failed assert for the in_n_frames check against input_frames_used: pa_assert((unsigned) data.input_frames_used == in_n_frames);
I ran pulseaudio through GDB and re-created error. Here are the exact steps I took to do that: Ubuntu 11.10 pulseaudio 1.0 1. Uninstalled pulseaudio and installed pulseaudio-dbg so I'd have symbols 2. Started pulseaudio under GDB 3. Re-created error: a) Started Chrome browser (version 15) b) Went to website that has HTML <embed> audio track (*not* HTML 5) c) pulseaudio crashed as expected and reported in this ticket Here is the GDB back trace at the time of this error: (gdb) bt #0 0x00007ffff66483a5 in __GI_raise (sig=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:64 #1 0x00007ffff664bb0b in __GI_abort () at abort.c:92 #2 0x00007ffff7b7bba5 in libsamplerate_resample (r=0x7f1610, input=0x7f1758, in_n_frames=441, output=0x7f1788, out_n_frames=0x7fffee01f3fc) at pulsecore/resampler.c:1214 #3 0x00007ffff7b7e0b9 in resample (input=0x7f1758, r=0x7f1610) at pulsecore/resampler.c:1137 #4 pa_resampler_run (r=0x7f1610, in=0x7fffee01f550, out=0x7fffee01f570) at pulsecore/resampler.c:1193 #5 0x00007ffff7b8ac91 in pa_sink_input_peek (i=0x7ece10, slength=17024, chunk=0x7fffee01f670, volume=0x7fffee01f688) at pulsecore/sink-input.c:875 #6 0x00007ffff7b911aa in fill_mix_info (s=0x68b5f0, length=0x7fffee021d18, info=0x7fffee01f670, maxinfo=32) at pulsecore/sink.c:913 #7 0x00007ffff7b939d7 in pa_sink_render_into (s=0x68b5f0, target=0x7fffee021d70) at pulsecore/sink.c:1152 #8 0x00007ffff7b93f29 in pa_sink_render_into_full (s=0x68b5f0, target=0x7fffee021e00) at pulsecore/sink.c:1236 #9 0x00007fffee044770 in mmap_write (on_timeout=false, polled=false, sleep_usec=<synthetic pointer>, u=0x6f0b10) at modules/alsa/alsa-sink.c:627 #10 thread_func (userdata=0x6f0b10) at modules/alsa/alsa-sink.c:1639 #11 0x00007ffff7931c78 in ??
