You’re right. I use it on my kubuntu box, where sound also is flaky.
I will try your script. Does it need you to install a “real” bash?
Didn’t test, won’t do it too soon. If so, I’ll report…

Thanks. For now I have audio, but I have saved your script and added it to qCommand.
I can confirm that I’m also having this issue with 4.1.0.24 on my XA2. This bug has persisted through several OS updates at this point - I would have thought failure of basic phone functionality would be quite a high priority for development of a phone OS, but it appears not…

Same here. Just updated to 4.1.0.24 on XA2. And audio only re-appeared after two reboots. Made us miss out on a relatively important phone call though. So, indeed, I agree this would be useful to again look into.
Hi @amaretzek,
is something missing from your script?
A single ` then no other ` to close?
By the way, the preferred way should be $(some command).
On Xperia 10 Dual SIM, I am running SFOS 4.2.0.19 since a few days. I have today for the first time no phone call audio. Everything else (sound-wise) works as before. Doesn’t seem to be a hardware issue.
What is there to try?
Yes, closing tick is missing…Thanks.
The command/script by @amaretzek did the trick for me too. Indeed, there is audio back.
This “bug” is annoying. Obviously.
Cheers
Thanks a lot! Can confirm that after killing both adsprpcd processes, i.e., just running devel-su pkill adsprpcd, resolves the issue for me when this happens. The adsprpcd processes immediately respawn and the audio is back during the phone calls.
I’ve used this trick several times now and so far worked every time.

Could someone discuss this topic at the next community meeting? Unfortunately I can’t attend during working hours.
Hi,
I have that bug on my XA2 (4.2.0.19), too. (It annoyed me since some 3.x version.)
Killing the “adsprpcd” process did the job for me, too.
I also use qCommand for this and I’m glad I have a workaround now until this issue finally can be fixed.
I have this problem since yesterday. I did not change anything until today where i upped the device. Still not working, no restart of pulseaudio, no kill of anything. Btw i only have one adaprpcd process. Just saying: under csd tool my audio works.
I have this bug too on XA2 dual sim and I am using two sim cards.
It appeared for me with 4.2.0.19, hoped to be fixed with 4.2.0.21 but it is still there.
In my case 4.2 brought two real issues:
- this call audio problem
- “no network” for android apps when working fine for the rest of SailfishOS/Linux.
Can i up-vote somewhere to increase Jolla’s attention on them 
?

I had (and still have) XA and XA2 Ultra for work and personal uses, and never had any issues with calls (save work calls at workplace, but that’s due to the local link / bad network). Well maybe sometimes, but nothing reoccurring at least…
Have you tried replacing the SIM card via your operator? It may also be faulty, and work “only most of the time”. Modem getting stuck/confused could hang services, too.
I encountered this problem constantly when using XA2, on two different SIM cards from different operators, problem also being encountered in various geographical areas. Neither of the SIM cards have had any problems with any other Xperias. I believe this very strongly suggests that the problem is not specific to some SIM cards / network details, but to some XA2 units.

That would be 2 SIM, 2 devices out of 2 daily driver, at my place…
And to add a straw to the camel’s back: I too got hit with this bug on my XA2 on 4.2.0. First time I noticed. killall adsprpcd helped, but of course that’s not how it should be.
I also noticed: when hanging up, the beep beep beep was audible. DTMF-tones by pressing numbers on the XA2 came through on the remote side. But, quite possible these tones are not actually transmitted as audio at all.

Topic was discussed at the last community meeting - #sailfishos-meeting log
Maybe someone can provide such a logfile
08:44:36 it’s the trick to actually catch the moment the subsystem fails (which can be in any point in time, not necessarily during the phonecall)

I experience the ‘no audio’ problem as well on a XA2 with 4.2.
In the past a reboot worked, however, since the Verla 4.2.0.21 update even reboots don’t work anymore, I NEVER have audio on normal phone calls. Doing an audio call with whatsapp is no problem, but when I call someone by simcard, or receive a phone call, no audio in either direction.
After two years of using Sailfish I see no option than switch to Android 
I always managed to have a phone without Google or Apple, before I used Windows Phone for almost 10yrs…
