Yes, it is still valid and the problem is not with my hardware (tested 
with other OS).

The attenuation need be more smooth. I think that it is very huge, so 
when the volume level is in 50%, nothing can be hear.

*Example* about what current happening:
- Max volume: 0dB
- 90% volume: -10dB
- 80% volume: -20dB
- 70% volume: -30dB
- 60% volume: -40dB
- 50% volume: -50dB

50dB attenuation is very higher! So, IMHO, the correct need be smooth:

- Max volume: 0dB
- 90% volume: -3dB
- 80% volume: -6dB
- 70% volume: -9dB
- 60% volume: -12dB
- 50% volume: -15dB
- 40% volume: -18dB
- 30% volume: -21dB
- 20% volume: -24dB
- 10% volume: -27dB
- 00% volume: -30dB
