[Satellite L745, Conexant CX20585, Speaker, Internal] No sound at all

[Jeremy Bícha]

I don't have any audio output through the laptop's internal speakers but I get audio fine if I plug in external speakers.

I can get audio working briefly by running

sudo hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0

as suggested at
http://lkml.iu.edu/hypermail/linux/kernel/1301.1/02917.html

but it doesn't last very long before the audio turns off again.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7-rc1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

When I tried back in June, the newer mainline kernels didn't work. When I tried going back in time, I couldn't find an Ubuntu kernel that was old enough to not have broken sound but new enough to still boot in Ubuntu 16.04 LTS.

I'm thinking you'd want me to identify a kernel that works but it may take me a while to get around to installing Ubuntu 12.04 or 14.04 on this computer to try older kernels.

[penalvch (penalvch)]

Jeremy Bicha, could you please advise which kernel you tested specifically?

To keep this relevant to upstream, one would want to test the latest mainline kernel (now 4.8-rc3) as they are released.
