I can’t continue in French in this chat (I’m required to answer in English), but I
can understand your French screenshots and I’ll keep the steps very explicit and with the French Windows menu names so you can follow them.
1) Yes, I can “read the attachments”… but right now they’re not readable
The 3 text attachments you mention (“services connectés”, “specs total pc”, “specs audio”) are arriving to me as
binary/unknown type, so I can’t extract the text content from them here.
So:
yes, please send them as plain text (copy/paste into the message), or re-upload as
.txt or
.zip that’s confirmed readable.
2) From your screenshots: your audio problem is NOT Realtek — it’s Intel Smart Sound / DSP drivers
Your screenshots show:
- Under “Autres périphériques” you have yellow warning icons on:
- Intel High Definition Audio
- Intel High Definition DSP
- Waves Audio Effects Component
- Under “Contrôleurs audio, vidéo et jeu” you do have:
- Under “Entrées et sorties audio” you only have Digital Output () (no Speakers).
- And importantly, under “Périphériques système” I can see:
- “Contrôleur audio de la technologie Intel(R) Smart Sound” (this is the SST/Smart Sound controller). That means it is present on your system, just not correctly driver-complete.
This combination typically means:
Windows detects the Realtek codec, but the Intel Smart Sound Technology (SST) / DSP path is broken, so Windows cannot build the normal “Speakers” endpoint → you end up with the red X / no output device.
(So when you say you didn’t find Intel SST: it appears in your screenshots as
“Contrôleur audio de la technologie Intel(R) Smart Sound”.)
3) What to do next (recommended order)
Because you have
Intel High Definition DSP showing as “unknown/problem”, the fix is usually installing Dell’s
chipset + Intel Serial IO + Intel Smart Sound / audio stack
in the right order, then the Dell/Waves components.
Step A — remove broken audio devices (clean slate)
- Device Manager (Gestionnaire de périphériques)
- Right click → uninstall (Désinstaller l’appareil) for:
- Intel High Definition Audio (the one with yellow triangle)
- Intel High Definition DSP (yellow triangle)
- Waves Audio Effects Component (yellow triangle)
- If you see the checkbox “Supprimer le pilote pour ce périphérique” (Delete driver software), check it.
- Reboot.
Step B — install Dell drivers WITHOUT SupportAssist
You asked: “Dell support page only says SupportAssist, how do I do otherwise?”
Options that usually work on Dell:
- Dell Command | Update (separate app from SupportAssist; commonly works better for drivers/BIOS)
- Manual driver download using Service Tag (Dell Drivers & Downloads → “Manually find a specific driver” / “View all drivers”)
- Driver CAB / offline package (some Dell models provide a CAB/pack used by IT departments)
Since I can’t see your exact model yet (because the attachments aren’t readable), I can’t point you to the exact packages by name. But the order should be:
1)
Chipset
2)
Intel Management Engine (ME)
3)
Intel Serial IO
4)
Intel Smart Sound Technology (SST) / Intel Audio DSP driver
5)
Realtek Audio (Dell package)
6)
Waves / MaxxAudio / Audio Effects component (Dell package)
Then reboot and re-check “Entrées et sorties audio”: you should see
Speakers / Haut-parleurs appear.
4) How to export the device list (easy)
Method 1: Built-in Windows report
- Win+R → type:
msinfo32
- File → Export… (or “Enregistrer”)
- Save as
.txt
Method 2: Command line (very useful)
Open
Terminal / CMD as admin, then run:
A) List problem devices (yellow triangles):
pnputil /enum-devices /problem /connected
B) Full device list to a text file:
pnputil /enum-devices /connected > "%USERPROFILE%\Desktop\devices.txt"
Upload/paste
devices.txt here.
5) One question to confirm (very important)
In
Device Manager, for
Intel High Definition DSP (yellow icon):
- Right click → Properties → tab Details → choose Hardware Ids
- Copy/paste the first 2–3 lines here
That hardware ID tells us exactly which Intel SST/DSP driver package you need.
6) What is “not OK” in your current config (summary)
What’s wrong right now is: the
Intel audio/DSP side is not installed correctly (Intel High Definition Audio + Intel High Definition DSP + Waves component appear as “other devices” with warnings), so Windows only exposes
Digital Output () and not normal laptop speakers. Your screenshot also confirms the SST controller exists as
“Contrôleur audio de la technologie Intel(R) Smart Sound”.
Send me this and I’ll tell you exactly which driver(s) you’re missing
1) Your
Dell model +
Service Tag (or just the model if you don’t want to share Service Tag)
2) The
Hardware Ids of
Intel High Definition DSP
3) Output of:
pnputil /enum-devices /problem /connected
Then I can tell you precisely what to install and in what order, and what you should see change in Device Manager afterwards.
