Try to disable "Loopback Mixing" mixer enum. % amixer -c0 set "Loopback Mixing" Disabled
This often leads to such a glitch.
Yess but without loopback, rear Linein does not work and I need it !
Do you really need it? It's a direct analog-loopback route from the input (e.g. line-in) to the headphone or such, and it has nothing to do with recording. (So it's just a sort of "monitor" route.) The recording works fine without this control. Its volume is controlled solely via "Capture Volume" in addition to "Mic Boost", etc. If you really need this monitor route, then such a glitch is unavoidable. This is the hardware feature of the codec chip.
Also, I don't know if is in someway related, I see this message in the log when I play with lmms or ardour:
snd_hda_intel 0000:00:1b.0: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
No, it's irrelevant, and this is mostly harmless, ignore it. -- You are receiving this mail because: You are on the CC list for the bug.
