I have a (Hoontech) soundcard with Trident 4DWaveNX chipset,
which is recognized by RTP 6.1A, but I don’t get any sound
output from Mediaplayer or other apps.
The mixer is running, and everything looks ok, but no output,
analog or digital. If I turn on mic boost or ADC/DAC loopback
in the advanced options I do however get a buzz or noise, so
there seems to be some sort of contact.
Anyone got this card running?
Any pointers?
