Re: Dell Vostro 5490 - no sound, no audio device
I desoldered the audio codec once again and measured the voltage drop on the signal lines 4,5,7 and 9 - 0.6V everywhere.
It looks like the hybrid is damaged...

Dell Vostro 5490 - no sound, no audio device
Hi, i've got problem with Dell Vostro 5490.
Board - Mantis CML 18788-1
Windows says "no audio device detected". The other functions work properly.
What i've done:
1. I checked motherboard
2. I changed audio codec (ALC3204)
3. I reflashed bios with clear ME
4. Audio is enable in bios
5. Both speakers are good
6. After installing the drivers from the Dell website, the devices visible in the manager:
- Audio for intel displays
- Intel Smart Sound Technology... -
