Could you get a more complete backtrace?

What is the guest OS, and configured sound card?

Thanks for you replay.
the os is linux ,sound card using ich6.
cannot get all the backtrace using gdb.
And when trach code,can get:
the backtrace:
update_mmtime_timeout_cb->spice_playback_channel_set_delay
->spice_session_set_mm_time->emit_main_context->g_signal_emit_main_context
->emit_main_context

It is ok when comment the spice_session_set_mm_time as fellow.


void spice_playback_channel_set_delay(SpicePlaybackChannel *channel, guint32 delay_ms)
{
    SpicePlaybackChannelPrivate *c;

    g_return_if_fail(SPICE_IS_PLAYBACK_CHANNEL(channel));

    CHANNEL_DEBUG(channel, "playback set_delay %u ms", delay_ms);

    c = channel->priv;
    c->latency = delay_ms;
 //del /*
spice_session_set_mm_time(spice_channel_get_session(SPICE_CHANNEL(channel)),c->last_time - delay_ms);*/
}

Can you still reproduce?
