no proper sound system & comment on aspire notebook

[Hugo]

i have a
Acer Aspire 5253-E354G50Mn (LX.RD502.012)
Ordinateur portable noir avec écran 15"6 - Processeur AMD E-Series E-350- Mémoire 4096 Mo - 500 Go - Carte graphique ATI Radeon™ HD 6310 Graphics (512 Mo) - Port HDMI - Graveur de DVD±RW - Lecteur de cartes 2 en 1 - Wifi 802.11 b/g/n - Windows 7 Familiale Premium 64-bit - Clavier AZERTY

i have no sound on headphone, and when i plug the headphone the laptop sound don't shut up

with 10.10 the outside sound shut up with headphone working ...

here just a comment about the screen thing : i found very stupid to have no choice in the gtk interface about the color deaph - the color is only availaible in 24bit - and i would like to select the deapth in the screen option window such as : 24 - 16 - 8 bit
also i misse a small color tuning in that window, very simple rgb tuning.

Take care !
