Firefox no audio--but look at all the multiple processes

Post by all41 » Sun Jan 07, 2018 10:32 pm

Code: Select all

inxi -S
System:    Host: Labonline Kernel: 4.4.0-98-generic x86_64 (64 bit)
           Desktop: MATE 1.12.0  Distro: Linux Mint 17.3 Rosa
Hello my fine feathered friends,
I need to be coddled a bit.

Have been using Palemoon for quite sometime but thought I would try out the newly patched FF 57.0.4
There is no sound from youtube videos and a FF banner reports I may need to install Pulse software. I checked Synaptic--pulseaudio and it's default libraries are installed and there are no broken packages anywhere.
Palemoon audio is normal, as well as all local audio.

I went to open pavucontrol and got 'Fatal Error-failed to connect to pulse audio' message.
Looking at the process list in the System Monitor I found pulseaudio is indeed not listed.


What is listed in the processes is now the main concern.

There are 25 instances of bioset
6 instances of getty
8 instances of ksoftirqd
50 instances of kworker
8 instances of migration
7 instances of scsi_eh
7 instances of scsi_tmp
all these are sleeping.
Does anyone recognize what would trigger all these processes?


I'm not sure how or when this all happened.

Troubleshooting the FF sound:
I have reinstalled pulseaudio & pavucontrol.
also renamed ~.mozilla without joy
pulse audio is enabled in the startup applications.

Any ideas regarding this mess?
Other than the pulse issue everything seems to be operating normally--but ugh! all those processes

Except "getty" all those you name are so-called kernel threads, not processes as such. It's a bit of kernel functionality split of into a process-like entity so that it is for example easily scheduled alongside regular processes but is much lighter weight; has no user space at all for example; does not take up any (user space) memory. Every example you list is normal and expected; for me for example,

Code: Select all

$ ps ax | grep kworker | wc -l
38
The 6 getty's manage your six virtual consoles on Ctrl-Alt-F1 to -F6 and are as normal.

Firefox complaining about Pulseaudio is not, and it being "in the startup applications" makes me wonder a bit, seeing as how it shouldn't (explicitly) be in Cinnamon -- but perhaps it should in MATE. Firefox appears to be compiled against pulse directly, i.e., not through for example gstreamer. You may want to check if you get comparable output to this:

Code: Select all

$ grep pulse /proc/$(pidof -s firefox)/maps
7f3a35f99000-7f3a39f9a000 rw-s 00000000 00:17 30                         /run/shm/pulse-shm-3532076147

This is on 17.3 as well. Otherwise though, I'll leave this up to a MATE user to compare...

[EDIT] ... although perhaps it's useful to specify that both listed libraries are provided by the libpulse0 package. I.e., may want to try a sudo apt-get install --reinstall libpulse0.

I checked a second workstation with identical hardware, using the same Mate 17.3 and same kernel.
The Processes list on that machine has zero instances of the processes in question-- however it does show pulseaudio.

This second machine has not yet been updated to FF 57.0.4, intramfs-tools 0.103ubuntu, or ruby1.9.3.484-2ubuntu1.6

That is not possible. Any Linux system has them; the only possibility is that you are checking the process list differently on both systems. It is a certainty that you see a very similar set of kernel threads on both systems when just using ps ax.

yes ps ax seems comparable--hard to tell because enumerated differently.

~ $ 
On the original system I logged off and back in as a new user and all the System Monitor gui
process listings are normal--zero instances of those multiple threads reported--zilch.
There is still no pulseaudio listed though.
Oh--one other thing I recall: while looking for pulseaudio I did a system reboot and the loading hung at a fail2ban call
Had to raise elephants; and then it booted normally.

Hi Shultz--thanks for that info.
I think it was your posts which led me to try palemoon in the first place--so thanks again.

I'd find that to be non-normal, being used to the command line. The issue probably was that kernel-threads are root-owned and that you were looking at listing produced by a with (gk)sudo started system monitor versus not. Or perhaps the MATE system monitor allows configuration in that respect; ps x would indeed also not show them.

Shall admit that that automated forum censor made me smile for once there. Well chosen. But fail2ban appears to be an automated firewall config thing, something I stay far away from. Wrt. Pulseaudio: I have installed on 17.3:

apt search pulse | grep ^i shows identical results with yours.
Here is what I see in System Monitor gui:
my old user:
old user.png
the new user
new user.png
new user.png (4.76 KiB) Viewed 513 times
the other multiples are similar, so the process list for the old user is very long.

Sorry then; no idea about the Pulseaudio thing. That thing being a pain-and-a-half to debug is one of its worst traits -- and that's saying something given its other traits.

Seems your old user is trusted more; is allowed to see processes owned by root; I'd quickly switch back. In case you're wondering: "bioset" is a kernel thread related to the kernel's lock /[O] subsystem. I have 14 such threads myself. Your 25 probably means you have more disks or are using encryption, I guess. In any case: nothing to worry about.

Hey thanks rene. You understand the Linux architecture much better than I.
It's been a long day so I will look after the pulse discrepancy tomorrow.
I will compare files/history/etc to find the culprit.

I tried to use it but it crashes since I use the Oxygen theme. I've read that with oxygen-gtk2-1.4.6.1 Palemoon works, but it isn't in the repos and I can't figure out where to find that package... that's 3 years old!!
Bummer... :?

Hello sichenia,

I suggest posing your inquiry as a new topic, with Oxygen and Palemoon compatibility as the subject.
This will attract more focused replies to your question.

Best regards

I need to be coddled a bit.

Have been using Palemoon for quite sometime but thought I would try out the newly patched FF 57.0.4
There is no sound from youtube videos and a FF banner reports I may need to install Pulse software. I checked Synaptic--pulseaudio and it's default libraries are installed and there are no broken packages anywhere.
Palemoon audio is normal, as well as all local audio.
This is because of a known incompatibility with older versions of pulseaudio and firejail. Try running

Code: Select all

firecfg --fix-sound
.
See https://firejail.wordpress.com/support/ ... pulseaudio; firecfg --fix-sound does the same as the listed commands (and is easier to use!). :mrgreen:

Hi Fred,
Thank you for reading. The code was not an immediate remedy for FF audio. I may need to update my firejail.
I see that you are a firejail tester, must run in the family--lol?
