Public bug reported:
I am running Ubuntu 16.04 LTS on my Acer Aspire E5-575 with kernel
4.4.0-53-generic #74-Ubuntu SMP Fri Dec 2 15:59:10 UTC 2016 x86_64 x86_64
x86_64 GNU/Linuxmy.
my system has no sound (built in speakers and headphone jack)and only shows a
dummy output. I have follow many forms for answers with no luck.
Playing around on my own I have found that the the issue seems to be with the
kernel. The problem seems to go away when reverting back to kernel
4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64
x86_64 GNU/Linux. when I switch to this kernel all audio functions appear to
function properly.
I do not know if anyone else is experiencing this or similar issue, or if this
has already been solved but for now using the 4.4.0-31 kernel seems to be the
only workaround for me at the moment.
Please let me know if their is any more information I can provide to
help solve this issue.
Hear is some information about my system:

Bug description:
I am running Ubuntu 16.04 LTS on my Acer Aspire E5-575 with kernel
4.4.0-53-generic #74-Ubuntu SMP Fri Dec 2 15:59:10 UTC 2016 x86_64 x86_64
x86_64 GNU/Linuxmy.
my system has no sound (built in speakers and headphone jack)and only shows a
dummy output. I have follow many forms for answers with no luck.
Playing around on my own I have found that the the issue seems to be with the
kernel. The problem seems to go away when reverting back to kernel
4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64
x86_64 GNU/Linux. when I switch to this kernel all audio functions appear to
function properly.
I do not know if anyone else is experiencing this or similar issue, or if
this has already been solved but for now using the 4.4.0-31 kernel seems to be
the only workaround for me at the moment.
Please let me know if their is any more information I can provide to
help solve this issue.
Hear is some information about my system:
