    initial v1  
    1818To further complicate matters, sometimes the HDA driver works great, yet media_server fails to send buffers to it, for 30 minutes or more after boot up (that's what I get with R1/b1, but never in the old hrev).
    1919So if you feel courageous, you could try to quit/disable media services and test with a bare-bones sine-wave generator that talks directly to the HDA driver, to make sure you lack of audio is not caused by the server, but is indeed caused by the HDA driver itself. I'm not sure where it is, it's been years.. It might be this one [https://git.haiku-os.org/haiku/tree/src/tests/add-ons/kernel/drivers/audio here].

     21EDIT: yeah that seems to be the one, it calls B_MULTI_BUFFER_EXCHANGE directly, and fills buffers with sin()
     22
     23EDIT: I'll go to my grave believing the lack of a media-bypassing sine wave "test" is one of the great mistakes Haiku made by the way.. So much time wasted, when a simple "test audio" button somewhere could have helped in many situations.
