Hi @misc,
when the kernel attaches the audio drivers, there is audible noise in the
headphones immediately. Way before sndiod is started. That noise is permanent.
I thought this is normal due to the audio hardware being crappy so did not
care. Helping someone with a hard drive, I booted that same machine into
Windows 10 from that harddrive and was supprised that there is no noise at all.
Is there something I can do to make it not produce noise on OpenBSD as well?
Windows loads some Realtek HD Audio driver whatsoever. Could it be that driver
knows about any hardware shortcomings and suppresses that noise in the driver
which the azalia driver does not and cannot do, as it is a common driver for
many devices? Where to start?
Regards,
