Yeah, you can see the freeze in the log. dsound is waiting for a signal from
winepulse that it never gets:

> 99253.592:0160:warn:dsound:DSOUND_mixthread wait returned 00000102!

The last traces we see from winepulse are:

> 99253.545:0162:trace:pulse:pulse_timer_cb got now: ce145e6, last time: ce11f3a
> 99253.545:0162:trace:pulse:pulse_read Readable total: 102, fragsize: 256

This shows the problem, there should be one more "after update" trace, like
there is in this chunk before that one:

> 99253.535:0162:trace:pulse:pulse_timer_cb got now: ce11d98, last time: ce0f82a
> 99253.535:0162:trace:pulse:pulse_read Readable total: 316, fragsize: 256
> 99253.535:0162:trace:pulse:pulse_timer_cb 0xe187f18 after update, adv usec: 9582, held: 160, delay: 10

But that trace never comes. It's stuck in pulse_read() somehow.

The patch you tried cleaned up the logic in pulse_read() and fixed a potential
integer underflow that could cause an effectively infinite loop, but apparently
that wasn't enough to fix it.

Are you capable of adding some traces in pulse_read() to see where it is
getting stuck?
