I have had a persistent issue for some time, it is with my sound. When i plug external speakers in i get sound, but the speakers on my laptop dont work...well they do for 20 seconds then they go quiet (20 seconds after rebooting)
My output from aplay -l is: List of PLAYBACK Hardware Devices card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: SB [HDA ATI SB], device 0: CX20585 Analog [CX20585 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0
I have checked in alsamixer if i was muted but it isn't. I cant change any volume ni alsamixer either. I'm thinking its reading the correct card but not the correct device.
I have tried hundreds of online solutions but none seem to have worked. I even tried downgrading to 12.04 but i still had the same issue.
According to alsamixer
Card: HD-Audio Generic
Chip: ATI R6xx HDMI
Can anyone help with this long term problem ive had, any help is appreciated
