https://bugzilla.suse.com/show_bug.cgi?id=1182823 https://bugzilla.suse.com/show_bug.cgi?id=1182823#c4 --- Comment #4 from Takashi Iwai <tiwai@suse.com> --- It turned out that it's no trivial task for the kernel driver; the channel map is assigned per PCM stream, and the PCM stream on HD-audio is shared for all different inputs, hence it cannot be specific to a certain audio route for the built-in mic. BTW, does the right channel sound silent? In the past, most of problematic built-in mics were the inverted right channel. Then adding both left and right became almost silence. If one channel is silence, OTOH, it'll lead to a half volume by summing. -- You are receiving this mail because: You are on the CC list for the bug.
