Hi,
Fedora got a bug report (https://bugzilla.redhat.com/show_bug.cgi?id=1512853) that Line Out stopped working between 4.13.9 and 4.13.10. Reverting 82d745a55779 ("ALSA: hda - Fix incorrect TLV callback check introduced during set_fs() removal") fixed the problem. I didn't ask the reporter to test on 4.14 since I didn't see anything explicitly tagged as fixing the issue. Any ideas?
It might be that the formerly saved asound.state brought the inconsistency. Try to remove the saved state (either /var/lib/alsa/asound.state or /etc/asound.state) after unloading the sound driver modules and reboot/retest.
In anyway, give alsa-info.sh output with the affected machine. Run the script with --no-upload option, and attach the generated file.
BTW, having the output of alsa-info.sh with a bug report helps analysis and debugging quite a lot.
So it'd be appreciated if you can ask it always as the first step for a bug report on Fedora regarding sound. Especially when it's a regression, the outputs on both working and non-working cases would be nice, so that we can compare more precisely.
thanks,
Takashi
