    33Edit: I've had to solve 20 catpchas to post (in Web+), dang it.

    5 Anyway, even though the above is only 4 HDA verbs, that gave more enough to work with for a couple days, to "retool". Confirmed that implementing just those 4 in haiku is not enough to get audio working. Now I'm ready for the full thing :-)

     7In other words,
     8
     9You should type both those lines in terminal:
     10
     11{{{
     12echo 1 > /sys/kernel/debug/tracing/events/hda/enable
     13echo 1 > /sys/class/sound/hwC0D0/reconfig
     14}}}
     15
     16That will trigger a (second) reconfiguration *after* tracing-logging is enabled, so that the log will contain the whole initialization sequence.
     17
     18The log should then contain many more than four verbs, it should be a flood comparable to this (partial) Haiku listing:

     22Welcome to the Haiku shell.

     47Then I'll ruthlessly adapt my code to match your log line-for-line. Thanks!
