Not sure if this belongs here, or in the hardware forum, so I’ll start here and let the mods move it if they see fit.
I developed a perplexing sound problem yesterday, and I’m hoping you guys can help me get it back to working correctly.
I’m running 11.4, and have HDMI out going from the computer to my TV. I’ve got audio out going from the TV to auxiliary 1 on a receiver. I also have a standard 3.5mm audio out going from the onboard mobo audio to auxiliary 2 on the receiver. For a while (basically since I installed 11.4), I’ve been using the 3.5mm audio output to auxiliary 2 on the receiver with no issues. I like this, because it lets me continue to listen to music while watching tv (sporting events where the announcers annoy me) or playing video games.
Monday night, everything was working fine, I stopped playing music, turned off the tv and the receiver (the computer is always on unless the power is out), and went to bed. When I got home from work yesterday and turned on the tv and receiver, I had no audio anymore. Plugged the 3.5mm cable from the computer into my phone, and heard music fine, so the problem isn’t the cable or the receiver.
After playing around with the computer for a while, here’s what I ended up with:
Yast shows two audio devices. When I first got home, card 0 was SBx00 Azalia (Intel HDA), and card 1 was ATI Technologies Inc. Playing a test tone on card 0 with the receiver on Auxiliary 2 gave me no output. Switching the ATI card to default and playing a test tone with the receiver still on Auxiliary 2 gave me no output.
Looking in the System Settings -> Multimedia listing, I see six audio options:
- HDA ATI HDMI, HDMI 0 (HDMI Audio Output)
- HDA ATI SB (ALC888 Analog)
- hw:0,0 (mouseover displays ALC888 Analog)
- hw:0,1 (mouseover displays ALC888 Digital)
- hw:1,3 (mouseover displays HDMI 0)
This may not have been the original order they were in, I started screwing around with making different cards default in Yast prior to opening this menu. With the receiver still on auxiliary 2, I get test sounds out of none of these options. However, if I switch the receiver to auxiliary 1, then I do hear test sounds from the two HDMI options.
So now I do have audio working again, although it’s coming through HDMI and into auxiliary 1 on the receiver. I’d really like to get back to having audio through the 3.5mm cable and into auxiliary 2 on the receiver, but I’m thoroughly perplexed and out of ideas here.
Any advice would be greatly appreciated.
