Internal Mic not getting any input #7

@zgrimshell i allowed myself to edit your issue slightly, so that the log-output is in a multiline codeblock (instead of one long singleline clodeblock) and put that in a |

Oh, great. it did look quite bad the copy so I am grateful that you tweaked it! |

For what is worth, in alsamixer it detects Intel HDMI/DP LPE Audio but says "This sound device does not have any controls" and I can switch to chtrt5645 which has all controls (and Internal Mic appears to be also on there but still not getting any input). |

Ido Schimmel says: ==================== mlxsw: Various fixes This patchset contains various small fixes for mlxsw. Patch #1 fixes a warning generated by switchdev core when the driver fails to insert an MDB entry in the commit phase. Patches #2-#4 fix a warning in check_flush_dependency() that can be triggered when a work item in a WQ_MEM_RECLAIM workqueue tries to flush a non-WQ_MEM_RECLAIM workqueue. It seems that the semantics of the WQ_MEM_RECLAIM flag are not very clear [1] and that various patches have been sent to remove it from various workqueues throughout the kernel [2][3][4] in order to silence the warning. These patches do the same for the workqueues created by mlxsw that probably should not have been created with this flag in the first place. Patch #5 fixes a regression where an IP address cannot be assigned to a VRF upper due to erroneous MAC validation check. Patch #6 adds a test case. Patch #7 adjusts Spectrum-2 shared buffer configuration to be compatible with Spectrum-1. The problem and fix are described in detail in the commit message. Please consider patches #1-#5 for 5.0.y. I verified they apply cleanly.

By calling maps__insert() we assume to get 2 references on the map, which we relese within maps__remove call. However if there's already same map name, we currently don't bump the reference and can crash, like: Program received signal SIGABRT, Aborted. 0x00007ffff75e60f5 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007ffff75e60f5 in raise () from /lib64/libc.so.6 #1 0x00007ffff75d0895 in abort () from /lib64/libc.so.6 #2 0x00007ffff75d0769 in __assert_fail_base.cold () from /lib64/libc.so.6 #3 0x00007ffff75de596 in __assert_fail () from /lib64/libc.so.6 #4 0x00000000004fc006 in refcount_sub_and_test (i=1, r=0x1224e88) at tools/include/linux/refcount.h:131 #5 refcount_dec_and_test (r=0x1224e88) at tools/include/linux/refcount.h:148 #6 map__put (map=0x1224df0) at util/map.c:299 #7 0x00000000004fdb95 in __maps__remove (map=0x1224df0, maps=0xb17d80) at util/map.c:953 #8 maps__remove (maps=0xb17d80, map=0x1224df0) at util/map.c:959 #9 0x00000000004f7d8a in map_groups__remove (map=<optimized out>, mg=<optimized out>) at util/map_groups.h:65 #10 machine__process_ksymbol_unregister (sample=<optimized out>, event=0x7ffff7279670, machine=<optimized out>) at util/machine.c:728 #11 machine__process_ksymbol (machine=<optimized out>, event=0x7ffff7279670, sample=<optimized out>) at util/machine.c:741 #12 0x00000000004fffbb in perf_session__deliver_event (session=0xb11390, event=0x7ffff7279670, tool=0x7fffffffc7b0, file_offset=13936) at util/session.c:1362 #13 0x00000000005039bb in do_flush (show_progress=false, oe=0xb17e80) at util/ordered-events.c:243 #14 __ordered_events__flush (oe=0xb17e80, how=OE_FLUSH__ROUND, timestamp=<optimized out>) at util/ordered-events.c:322 torvalds#15 0x00000000005005e4 in perf_session__process_user_event (session=session@entry=0xb11390, event=event@entry=0x7ffff72a4af8, ...

Ido Schimmel says: ==================== mlxsw: Various fixes This patchset contains various fixes for mlxsw. Patch #1 fixes an hash polarization problem when a nexthop device is a LAG device. This is caused by the fact that the same seed is used for the LAG and ECMP hash functions. Patch #2 fixes an issue in which the driver fails to refresh a nexthop neighbour after it becomes dead. This prevents the nexthop from ever being written to the adjacency table and used to forward traffic. Patch Patch #4 fixes a wrong extraction of TOS value in flower offload code. Patch #5 is a test case. Patch #6 works around a buffer issue in Spectrum-2 by reducing the default sizes of the shared buffer pools. Patch #7 prevents prio-tagged packets from entering the switch when PVID is removed from the bridge port. Please consider patches #2, #4 and #6 for 5.1.y ==================== Signed-off-by: David S.

So I have this Intel Atom based standalone tablet (nothing fancy or well known company) and I got on it Neon (and Ubuntu derivate) with Plasma. The installation went fine, overall performance is nice but there was no audio. Using your scripts and fixes, I rebuilt audio parts for 4.20 and it went fine, now I had great audio output (it is multichannel output so I needed to choose that in settings) and while it recognizes the mic (you can see it in settings and all) it doesn't detect any input.
I will be happy to attach any info and screenshots if needed but for now I will leave the output recommended in your fix wiki:
