Created attachment 946588 [details] alsa-info showing resource conflict Alsa does not properly detect audio device and/or output sink (Realtek ALC889A on GA-P35-DS5 / ICH9 motherboard) Fedora 21 does not properly configure my audio device and/or output sink (Realtek ALC889A on GA-P35-DS5 / ICH9 motherboard). The problem is not new to fedora 21 but arose with fedora 20 (if I recall correctly). There are multiple reports of this problem in other distro-forums (such as https://bbs.archlinux.org/viewtopic.php?id=180437). I managed to produce a script that resets audio configuration and selects the correct sink as a workaround. The first part of the script involves removing pulseaudio configuration, but this can now be commented out. If I recall correctly, this actually was necessary early in fedora 20. Currently, I automatically start the script after logon to cinnamon using a 'Startup programs' entry. But, probably there's more people out there frustrated with this problem, who won't figure this out and just give up replacing xp with linux. Alsa-info output will be attached. One of these files reports a resource conflict involving IRQ's. I tried to hint the snd_hda_intel model using: options snd_hda_intel model=6stack which should be ok for ALC889A models (6 jacks back, 2 front). This does not make a difference; still need to assign the sink using pacmd. I'm not sure whether the LXDE LiveCD is supposed to support sound, but I tried the fedora 20 version and it does not give me any sound. Last week, I separately installed Fedora 20 with Gnome 3 desktop which also did not give me any sound by default. Cinnamon sound settings only show output sinks 'Digital Output (S/PDIF)' and 'Analog headphones', but no 'Analog Output'.
