Fedora 32 ... installed new Nvidia video card and lost sound from sound card
by Unknown3rdParty from LinuxQuestions.org on (#5FGWG)
I recently installed an Nvidia-based Asus video card; I also have an Asus Xonar sound card. Until I installed the video card, sound had been working perfectly; my workstation is connected to a stereo receiver via a Toslink cable and it has been delivering glorious 5.1 sound.
To install the video card, I had to re-arrange cards: the Xonar is no longer in the same slot because that slot is now obscured by the video card. At this point, the PulseAudio volume meter actually shows sound being generated, and I've just disabled the sound on the monitor (thanks to a posting here). The receiver and speakers are still working correctly because I can switch to Tuner and pick up radio stations and broadcast sound. The receiver is not muted and I've disabled the Nvidia in PulseAudio ... but I still can't get sound over the sound card.
I know I caused this, and I think I know why I still don't have sound--probably a configuration file or entry which is still pointing at the wrong location--but finding and solving it has escaped me.
For starters, I have uploaded the output of my alsa-info to http://alsa-project.org/db/?f=439864...54f8cae047b5a7.
