changed milestone to %[device] PinePhone support

added category::device help wanted labels

speaker

Works fine but when active it emits a high pitched noise which is quite unpleasant. It's not as annoying because the speaker gets switched off automatically when not in use (after 5 seconds or so).

main microphone

Microphone works fine for me after !1113 (merged)

headset

Works fine

headset microphone

Works fine for me after !1113 (merged)

jack detection

Not implemented in kernel

headset buttons

Not implemented in kernel

Dumping chat logs:

z3ntu: headphone jack detection should be reading a single register (0x318 HMIC Status Register -> Bit 6 -> 0: no jack, 1: jack!). Also 0x1D Jack & Mic detect Control register has to have Bit 7 set to 1 to enable the detection.

MartijnBraam: yes but the jack detect interrupt is in the wrong subsystem in linux

anarsoul: z3ntu: IIRC the problem is that interrupt is in digital codec and actual jack status is in analog codec

anarsoul: so one should export interrupt-controller and another should use it

anarsoul: it's not elegant but I don't see another way to do that

anarsoul: also someone needs to implement it :)

The speaker noise issue seems to be a hardware design issue that has been fixed in the 1.2 PCB

By Martijn Braam on 2020-04-24T21:51:48

We'll see soon enough (my 1.2 should be arriving next week I hope)

By Luca Weiss on 2020-04-24T21:59:58

The speaker noise is there with my CE edition PinePhone. Anyway to debug?

By Shaun Ren on 2020-08-06T08:28:59

This isn't fixed yet, but there's a separate issue: #439 (closed)

By Oliver Smith on 2020-08-06T08:28:59

I have no audio output on a fresh install of pmOS with phosh on the PinePhone CE, installed over JumpDrive. I've restarted the device but I have no audio output at all. I notice that Speaker is not here reported as working. Should this "just work" on boot/reboot with the current state of the OS or do I still need to apply some settings?

https://wiki.postmarketos.org/wiki/Phosh would suggest I need to change the configuration but the option it speaks of (Make a phone call) is not present. The available Output Devices are Multichannel Output - Built-in Audio and Headphones - Built-in Audio. The available Input Devices are Multichannel Input - Built-in Audio and Analog Input - Built-in Audio.

Within dmesg, my 1.2 CE board is reported as a 1.1 Braveheart board.

Also, my volume keys are not working, but this appears to be a known phosh issue that is being addressed here: https://source.puri.sm/Librem5/phosh/-/issues/308.

By T. H. Wright on 2020-06-17T00:22:10

I have the same issue as @thwright on my braveheart (1.1), both on phosh and plasma-mobile on the edge branch (master).

I could also verify that the audio works on the stable branch (v20.05) on both phosh and plasma-mobile but i was unable to pinpoint the package causing the problem.

hey, about the audio breakage on pinephone, this has just been fixed with !1323 (merged).

By Antoine Fontaine on 2020-06-17T13:36:55

Great! I will check it out when I can. This fix should work for phosh and Plasma Mobile then?

By T. H. Wright on 2020-06-17T13:36:55

I can confirm it's fixed, I just don't understand why "introducing a typo" (audio -> audi) fixes it. Shouldn't the proper fix be fixing the typo somewhere else?

By Pedro Moreno on 2020-06-17T14:02:25

ALSA a while ago introduced rule in UCM parser where profile names shouldn't exceed 16 characters (16 with null-terminator) and now Pulseaudio added this rule too.

marked the checklist item speaker as completed

By Antoine Fontaine on 2020-06-17T09:22:09

I believe speaker works. It's even the default output.

By Antoine Fontaine on 2020-06-17T09:23:07

Am i missing something, or do we have another issue to include switching audio through modem when accepted a call, and revert after a call?

By Steven Vanden Branden on 2020-06-17T18:12:09

About the last two, the kernel support for autodetection may be missing, but switching to it manually works. (I've used GNOME's Settings to switch.)

By Antoine Fontaine on 2020-06-20T12:20:06

Jack detection & headset buttons are implemented in https://gitlab.com/pine64-org/linux/-/merge_requests/19 (which isn't merged yet)

By Luca Weiss on 2020-06-27T12:56:41

I have been trying for more than a day to get audio capture working, with no success.

The steps I am attempting:

alsaucm -c sun50i-a64-audi set _verb HiFi set _enadev Mic set _enadev Speaker to start with a clean slate
arecord -vvv --format=dat --device=hw:0,0 /dev/null to monitor the capture

What I observe:

arecord is reporting Max peak (12000 samples): 0x00000000 # 0%, so in other words, it is not getting sound from the microphone (not even noise).
cat /proc/asound/sun50ia64audio/pcm0c/sub0/status shows state: RUNNING
When I enable AIF1 Loopback (WARNING: loud) in alsamixer, I hear the microphone, so the audio should be getting through at least up until the AIF1 interface.

From the above observations, I suspect that the issue is somewhere in the kernel, and I am kind of stuck on this right now. Any help would be appreciated :)

Other info:

I have the 5.7.0_git20200705-r1 kernel.
Audio playback from the CPU does work.

By György Kurucz on 2020-08-06T08:39:57

Are you using edge or stable channel?

Does the microphone work in calls? I'm not sure anyone has tested recording audio outside of calls yet - I certainly did not. For calls, the audio profile automatically gets switched in Phosh to the "Make a phone call" profile, which will route the microphone through the modem.

Here are the audio profiles, maybe they need to be tweaked: https://gitlab.postmarketos.org/postmarketos/pmaports/-/tree/master/device/community/device-pine64-pinephone/ucm

The APKBUILD shows where they get installed. Note that the path is slightly different in the stable channel due to a different pulseaudio version ("audio" instead of "audi"):

By Oliver Smith on 2020-08-06T08:39:57

I am using edge.

I am specifically interested in audio recording by the CPU. (I have not tested it in calls, but I have no reason to believe that it would not work, since AFAICT the microphone is routed directly to the modem on AIF2.)

I tried many different configurations in alsamixer, and was unable to find any combination that would get the capture working, so the issue is probably not with the audio profiles. (Yes, I am aware of the "audi" quirk.)

I have created an issue for the upstream kernel: pine64-org/linux#28

By György Kurucz on 2020-08-06T09:11:03

As @philm suggested, pine64-org/linux@4c0b416fa83cfc2bcc6296a9e1f6af4acdc06096 appears to fix this.

By György Kurucz on 2020-08-06T14:22:39

@kuruczgy there is a regression in 5.7 kernel series regarding audio recording. It works on 5.6 branch, though ...

By Philip Müller on 2020-08-06T09:53:12

@ollieparanoid what about this manjaro jack detection patch?

By Jakub Zdanowicz on 2021-01-22T00:06:47

@ollieparanoid?

By Jakub Zdanowicz on 2021-01-22T00:06:47

if you want to have it included (and have tested it!) please open a MR. You can also directly ask megi to integrate it (if you have tested it)
