James,
on a second thought, I found an issue sufficiently important to warrant its own
report: bug #30118 is about sound stopping after:
 62.190:alsa_write_best_effort writei failed, recovering: -32 (Broken pipe)

BTW, 44800 is nothing standard. Did you mean 48000?


Antonio,
please make sure your logs always include both test results like:
render.c:945: Clock Frequency 48000
as well as the traces like:
41.667:0027:trace:alsa:alsa_write_data pad: 4439
using the >>render.log 2>&1 trick.  Your latest log solely contains the former
and it's impossible to tell what caused:
render.c:1243: Test failed: NULL buffer returned

>I get stuttering plus the last GetAudioEndpoint always set to "default".
That means wine did not manage to open the other devices.  For instance,
something like hw:0 will be unavailable while jackd grabs it.  However, "amix"
should have worked via ALSAOutputDevices in the registry.

comment #15 >Stuttering is *not* present when running the render.log
comment #30>Whatever device I choose I get stuttering
Now you lost me.  What's the difference between those two test runs of
mmdevapi:render?
