[SOLVED] No sound from any source

Hi,

I cannot get my fresh install of 16.0.4 (64 bit) to output sound from any source. A reinstall of alsa-base and pulseaudio with the following did not work.

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

I've tried a couple of other options, including the removal of alsa-base.conf followed by a reboot and restore of the file.

It looks like ALSA simply does not support my sound card using the current configuration. Details from /proc/asound/oss/sndstat

Sound Driver:3.8.1a-980706 (ALSA emulation code)
Kernel: Linux xxxAspire-5742 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64
Config options: 0

Installed drivers:
Type 10: ALSA emulation

Card config:
HDA Intel MID at 0xb4400000 irq 27

Audio devices: NOT ENABLED IN CONFIG

Synth devices: NOT ENABLED IN CONFIG

Midi devices: NOT ENABLED IN CONFIG

Timers:
31: system timer

Mixers: NOT ENABLED IN CONFIG

Is there an alternative to ALSA and PULSE? Or, is there a way to manually force ALSA and/or PULSE to recognise the sound card?

Hi @ottimo_massimo,

Hi @wolfman, thanks again for another reply. It’s really appreciated. I came across that link and tried step 1 with no luck. I was hoping to avoid the other fifteen steps, but it looks like I’ll have to plod through it! I’ll let you know how it goes.

After further tinkering, the HDMI and headphone outputs work. I think the laptop's speaker may just be busted. Alsa threw a crash log when oem-audio-hda-daily-dkms was installed with

sudo apt-get install oem-audio-hda-daily-dkms

I think I'll park this for now!

Thanks again for your help with this.
