[SOLVED] (Bluetooth) No audio after using flashplayer-standalone

arbitarycounterfactual · 2024-09-24 15:54:52

I wanted to run some old swf files and came to find out about flashplayer-standalone. I just wanted to obtain the binary from the aur package and run it directly. I ran makepkg -so and ./src/flashplayer <url-to-swf> to test it out.

It ran fine except it played audio in the speakers. I reconnected my headphones while the program was running. Doing so somehow broke the audio from the headphones (or any other bluetooth playback devices).

Flashplayer doesn't support pulseaudio but it also shouldn't generally lead to "no audio" and you'd rather have used it via the pulseaudio-alsa bridge.

What do you get from

sudo fuser -v /dev/snd/*
aplay -lL
systemctl --user status pulseaudio pipewire wireplumber
pactl list cards
pactl list sinks
pactl list sink-inputs

Got audio with pulseaudio -k && pulseaudio --start. But not sure why pulseaudio stopped stopped playback on bluetooth devices all of a sudden!

V1del · 2024-09-24 16:25:54

Can you post these outputs? You might be running multiple implementations of the pulseaudio/BT API and a trigger (e.g. pipewire getting invoked via pipewire-alsa, which might bring up wireplumber, which might steal BT devices from pulseaudio) could give you a logical conflict.

You should btw always restart pulseaudio with

systemctl --user restart pulseaudio

to guarantee internal session consistency.

I don't have any other user space sound services installed apart from pulseaudio/bluetooth. I don't see a scope of such conflict.

any pointer to a read up on how to set this up? Is it just basically an install through pacman? Will it help flashplayer play audio over bluetooth?

V1del · 2024-09-24 17:02:27

Install pulseaudio-alsa and not doing anything else should be the deal. The fact that aplay -L does not point to a proper default device suggest some manual asound.conf/.asoundrc being created, which you should remove in case.

I see a combined sink, the fact that flashplayer will likely have "stolen" the actual physical card from pulseaudio could've lead to some weird interaction issue between said combine sink and the BT sink created by pulseaudio, as pulse would've been unable to maintain the combined sink as the on board card was already occupied.

arbitarycounterfactual · 2024-09-24 18:30:54

Now, I do remember that a manual configuration was done with .asoundrc, for a certain issue that has to do with no audio being played 3.5mm headphone jack. Here it is:

pcm.!default {
    type plug
    slave {
	pcm "hw:0,0"	
    }
}

ctl.!default {
    type hw
    card 0
}
defaults.bluealsa.service "org.bluealsa"
defaults.bluealsa.device "38:8B:59:93:B8:76"
defaults.bluealsa.profile "a2dp"
defaults.bluealsa.delay 10000

Could you elaborate a bit? Which line of the output seems to be the deal? Removing the contents or the .asoundrc itself might reinstantiate that older issue.

Coming onto the real concern, does removing the combined sink solve this?

V1del · 2024-09-24 20:14:48

The "default" device is not present (compare aplay -L after removing this file), which happens when you forcibly (pcm.!default ) override the standard default device (to make it show up in aplay -L you'd add a

 hint {
        show on
        description "custom default ALSA Output"
    }

or so...

This has absolutely no relevance to any headphone jack concerns regardless (you'd configure those in amixer/alsamixer, and the config you created here is literally the logical default if you don't do anything at all) but especially not if you are talking about pulseaudio audio clients (anything natively using pulseaudio is going to ignore this file resp. pulseaudio itself is going to ignore this file, you configure pulseaudio default sinks in pavucontrol and pactl and friends). The fact that you have a bluealsa config in here is now much more likely to be the real issue. Flashplayer is likely the first application you've used that actually looks at the .asoundrc (due to it only supporting the ALSA API), when taken up on that offer, likely bluealsa took control of the headset (away from pulseaudio) which is why you weren't able to reinstate that without reloading pulseaudio.

So in summary, get rid of this configuration and uninstall bluez-alsa and install pulseaudio-alsa instead. That way pulseaudio will be the one daemon that controls all other audio APIs
