can't play sound if two sound softwares are open [Solved]

[22decembre]

Hello

I am new to sabayon and improving it every day yet.
Currently, my problem concern the audio. When I run several audio programs, I can only hear one of them.

An example would be more explicit :
I will have a look on a youtube page. If ten minutes after any sound finish, I open Amarok, no sound get out ! I will have to close the youtube page (whereas it doesn't makes any sound yet !)

For me, it looks like oss. But I don't know because I think I have never use it !

I have alsa compiled in the kernel, but no oss, and a intel inside card (acer laptop)

This is my /etc/modprobe.d/alsa.conf

Code: Select all

# ALSA portion
# OSS/Free portion

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
##  ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
##  OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##

option snd-hda-intel model=acer

# OSS/Free portion - card #1
##  OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

Ur audio issue may be related to the fact that everything is using pulseaudio now, and then goes into alsa.

try as root in a terminal "equo install pavucontrol paman" and use pavucontrol to change audio settings for pulse as per application. So apps that rely on KDE for audio privileges and not directly on alsa or pulse, now go to pulseaudio.

Make sure you are updated with latest stuff, a lot of changes from a fresh install

22decembre, most of the posts in the thread mentioned by wolfden tell you how to disable PulseAudio, which wouldn't solve your problem. if you're still not successful, have a look at the thread Getting PulseAudio to cooperate, which also shows some screen dumps of the PulseAudio configuration.

If you're lucky, PulseAudio works well: for example as I type this I am talking to someone on Skype with my headphones and at the same time I'm watching YouTube videos (about what we're discussing) that I can hear but he can't (i.e. it works as intended). I can also play music using a media player at the same time and can hear that too (but he can't). So PulseAudio does have its uses. We're discussing various sporting activities and watching different YouTube videos as we talk on Skype; PulseAudio makes this possible and allows us to do it simultaneously.

By looking lshal, I have found several Oss entry, should it be ok ?

In another thing, should I erase some sections from the make.conf ?

Solved : simply mv pulseaudio executable... !

[Darksurf]

lol, thats not solving anything, thats just an ugly hack with no fix in sight.

Oh, well. When 5.2 is released, you can just backup your important data and install 5.2 and this will be fixed.
We fixed this thanx to some great Sabayon Staff , and now alsa and pulse play nice and work properly together as they should.

Of course this is just one route, this isn't the only way to fix ur issue.

Be sure to thank them for all the hard work and time they donate to fix issues like this to serve you up a great rolling release.

[22decembre]

Every thing's really good now !

I have created /etc/asound.conf, which seems to be needed but not created natively !

By the way, I have compiled a kernel without oss in the alsa section. Do you think it's a good idea ? Really ? Pulseaudio doesn't makes another oss emulation layer, does it ?

Of course, I keep my previous kernel in the corner...

[Fitzcarraldo]

So 'PulseAudio Volume Meter (Capture)' and 'PulseAudio Volume Meter (Playback)' both show a moving bar when you are recording or playing audio now?

Regarding OSS, no need to disable anything in the kernel. I didn't and everything works fine.

[22decembre]

Yes, all is ok...

I will get back to my previous kernel... It was a try, in appearance nothing change !
