Title:
[NJ5x_NJ7xLU, Realtek ALC293, Speaker, Internal] No sound at all (or
so KDE "thinks")
Status in alsa-driver package in Ubuntu:
New
Bug description:
This is an odd one (or so it seems to me)...
Sometimes, after booting, my log is filled with messages similar to:
[ 208.746660] snd_hda_intel 0000:00:1f.3: No response from codec,
resetting bus: last cmd=0x20a3b000
[ 209.758633] snd_hda_intel 0000:00:1f.3: No response from codec,
resetting bus: last cmd=0x20a70740
[ 210.770511] snd_hda_intel 0000:00:1f.3: No response from codec,
resetting bus: last cmd=0x20bf0015
See bug #1886626 ("after login to gnome with snd_hda_intel 0000:00:1f.3: No
response from codec")
for a very similar problem; or at least the same-ish message.
The KDE volume thingy says there are no audio input or output devices.
I cannot configure anything audio-H/w related with KDE.
HOwEVER, whilst generating this bug report with apport-cli(1), the tests it
ran clearly showed
(heard!) the built-in (internal) speakers are working. Intrigued, I tried a
wireless Bluetooth
headset (it also worked), a wireless USB headset (also worked), and a wired
headset (also worked).
So there *is* sound, but KDE thinks there is no H/w... SOMETIMES.
At other times, everything is fine. There is no known pattern here (e.g.,
warm- or cold-boot
does not seem to matter, etc.). And then, just to confuse things further, at
least once the
system booted up in the KDE-no-sound state (complete with module "No response
from codec"),
but later (a few minutes?) began to work; a check of the log (dmesg(1))
showed those messages
had stopped and everything from then on appeared normal. (I'll see if I can
find that incident
in the logs, *IF* I can, I'll attach it later.) That "not"-working to
working does not usually
seem to happen (that one incident may be the only time it has happened?)
I have no idea if, when in the KDE-no-sound state, if I can control the
volume from the computer.
I have also NOT tested the input (microphone(s)) whilst in the KDE-no-sound
state, but I presume
it's like the output (works but KDE doesn't know it?).
It sort-of looks like, at the moment, to me, there is sometime amiss in the
"kernel sound stuff"
which is having a knock-on effect on the "KDE sound stuff". Apologies I
cannot be any more
specific... ;-(
