Description Óscar García Amor 2017-11-22 09:43:18 UTC
In my Z400 workstation after update kernel to 4.13.3 or newer I have or very low volume sound (in 4.13) or no sound (in 4.14).

My sound device is a Intel Corporation 82801JI (ICH10 Family) HD Audio Controller.

All problems seem related to kernel commit 99b5c5bb9a5435a5ae5d46445ac0f2bf6aa5ee52. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=99b5c5bb9a5435a5ae5d46445ac0f2bf6aa5ee52

Could you give alsa-info.sh outputs on both working and non-working kernels?
Run the script with --no-upload option, and attach the outputs to Bugzilla (don't paste).

Working again after install alsa-utils and reboot!
Comment 5 Óscar García Amor 2017-11-22 11:14:42 UTC
Running the alsa-info.sh script I discover this behavior:

- With 4.9.64-lts works well (with or without alsa-utils).
- With 4.14.1 no audio if the package alsa-utils is not installed.
- With 4.14.1 booted with alsa-utils package installed works well.

Install the alsa-utils package in 4.14.1 don't fix the issue until system reboot.

Thanks, this clarified the problem in the previous fix.

Please try the patch below.  It should bring the initial volume as expected again.

Sorry for delay. My computer take some time to compile the kernel.

With the patch the issue is fixed :). Sound works well with or without alsa-utils.
