Creative Sound Blaster card slips to headphones mode
by mike acker from LinuxQuestions.org on (#4YBGB)
I installed a Creative Systems / Sound Blaster SB1570 in my Debian-10 system today.
This was done because the ROG STRIX B450-F MoBo built-in audio would drop into a 60 hz AC hum whenever no sound app was playing -- e.g. if a video were put on pause.
The SB1570 seems to fix this, BUT: the SB1570 does not have a dedicated LINE-OUT port: it has a shared headphone/line-out port -- and it seems to shift into headphone mode when I don't want that.
So, the question is: can I set a parameter someplace to force the SB1570 into LINE-OUT mode 100% of the time ?
hopefully
