[HP Pavilion x360 Convertible 14-ba1xx, Realtek ALC295,
Thank you for reporting this bug to Ubuntu.
Ubuntu 19.04 (disco) reached end-of-life on January 23, 2020.
See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
We appreciate that this bug may be old and you might not be interested
in discussing it any more.
I have the same problem that is initially solved in the same way.
Closing the laptop and opening it again seems to restore sound. Running
Ubuntu Studio v19.10 amd64 on a brand new, just bought HP Pavilion

Retried with booting to windows, warm rebooting to Ubuntu, confirmed

Apologies for the delay in getting back.
I booted into windows, rebooted into Ubuntu without shutdown, sound is
not working. Ran speaker-test in a terminal and youtube video in
firefox. No sound.
Ran the command sets one by one.
No sound came out after any set.
Please let me know what else need
Please do a test:
When speaker doesn't work, run,
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x8
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x6ac8
// check if speaker works now
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0xd
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x
Sorry, it was my fault. Correct #5, it should be "echo 1 >" instead of
"cat 1 >". Anyway you generated the alsa-info.txt with coeff in the #7
and #8.

Here is the alsa-info for the case where I booted into windows, shutdown
completely, then boot into Ubuntu. Sound is working
Same permissions issues exist for writing the alsa parameters. I was

Sorry, looks like I did not follow the full instructions. Here is the
file with the proper name.
I am also documenting the steps so that somebody else can follow the
instructions as well.
This is after booting into Windows and then rebooting into Ubuntu
without a Windows shutdown
Stop pulseaudio
I was unable to run the dump_enable command as I was getting permission
denied even when running as sudo su. This is the alsa-info when I booted
into Ubuntu while rebooting from Windows and when there is no sound. I
will do the same while booting from a shutdown state from windows.

Please collect two alsa-info.txt with dump_coef enabled:
1) boot into windows, shutdown, boot into ubuntu linux, make sure the
speaker works, then sudo su; cat 1 >
/sys/module/snd_hda_codec/parameters/dump_enable; collect an alsa-info
.txt-spk-work by running alsa-info.sh
2) boot into ubuntu linu
I believe that this is still a bug. Will be happy to help debug /
provide more info.

Thanks for looking into this. The system comes pre-installed with
Windows. The speaker works in Windows but I have not gotten it to work
yet on Ubuntu yet.
I played around with hdajackretask, snd-hda-intel model but nothing
seemed to work.
After I had posted this bug I was playing around with dif
Did the speaker ever work before?
