I own an Acer AspireOne722
- AMD C-60 APU
- 2Gb RAM
- Conexant CX20588 sound card.
I use Ubuntu 12.04LTS
Output is perfect: both speakers and headphones work fine.
I have troubles with input: the internal mic was not enough powerful for skype calls so I tried to switch from "Internal Mic" to "Mic", realizing that the device called "Mic" (expected to be the 3.5mm mic port) is actually a loopback device: it gets audio stream directly from my output!!
Example: I play a song with my mp3player and I use gnome-sound-recorder with "Mic". I obtain to record the song played!!!
I tried to change alsa drivers from linuxant without improvements. Even Alsamixer seems not to solve: i think that the problem is located at lower layers of abstraction.
