Sound not working on Dell Latitude 7350

[MatteP]

Hi everyone,

I've recently installed Debian on my laptop Dell Latitude 7350 but the sound is not working.
On the same laptop I used top have problems with the sound (when I had installed, before Debian, Antergos) but after searching around I had managed to solve the issue.
This time instead, although the problems seem to be the same, I don't manage to have a working sound card.

The weird thing is that now my sound card seems not to be detected anymore.

In fact in the past, with Antergos, the out of

Code: Select all

aplay -l

was

Code: Select all

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]

while now it is

Code: Select all

aplay -l

  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The output of

Code: Select all

cat proc/asound/modules

used to be

Code: Select all

0 snd_hda_intel
1 snd_soc_sst_broadwell

and now it's only

Code: Select all

0 snd_hda_intel

But it seems indeed that HDA Intel HDMI is not capable to play any sound (and in fact, in the past, with Antergos, I used to set the settings of the other sound card to have a working sound)

Any idea...suggestions?

Thanks in advance,
MatteP

Do you think maybe it needs a firmware? There might be something in dmesg if so.

Seems you have been having trouble on this machine for awhile...

I found this link, might have some good info. I use a little Dell Mini, it's pretty awesome with KDE, but needs a little more ram.

Hi bw123!

Yes...unfortunately I've been having problems for some time to date.
And it's been an issue because this one should be my work laptop but I've been forced to use my personal older Samsung laptop (but still with Debian on) for the most of the things.

I'll check your suggestion out.

Thanks,
MatteP
