Alsa, no sound

lambd0x · November 4, 2015

Hello everyone I've just finished installing Funtoo in my desktop and managed to get almost everything to work, but still I've not been able to configure sound with alsa.

I've installed awesome and created a widget for sound control that calls up alsa. But every time I try to open alsa from it I get an error, just the same if I try it directly from terminal:

lambd0x@lambd0x ~ $ alsamixer
cannot open mixer: No such file or directory
lambd0x@lambd0x ~ $ sudo alsamixer
cannot open mixer: No such file or directory

And the widget doesn't show any interface, just default. What can I do to get it working?

Thanks for your time :)

I managed to get everything working including Firefox. Thanks for all the help.

Same thing.

lambd0x · November 4, 2015

How can I fix this problem?

Another thing, I just rebooted my machine and in the loaded modules I saw a message saying to unmute my audio card in /var/lib/alsa/asound.state right now I went there and this file doesn't exist

Hi, I found a way to get alsamixer working and managed to change it's configurations. It does identify: default, HDA Intel HDMI(chip Intel haswell) and HDA Intel PCH(chip Realtek ALC887-V). However just the last one shows up channels to be configured. I've unmuted Master, but no sound yet.

The results your requested...

I've been looking for other clues and came across profiling and mix-ins. Wouldn't be necessary to use them in order to play something?

I have setup a core flavor so far.

Details above:

!!! Found 2 make.conf files, using both '/etc/make.conf' and '/etc/portage/make.conf'

I also ran the alsa script again and it gave me what follows:

By the way, as I did get alsamixer working from removing every older config file of it and reinstalling it the emerging again alsa-lib my volumeicon recognizes the configs set by alsamixer.

The output from alsainfo looks good. HDMI audio is set to default card 0.
If you don't have speakers that connect to HDMI you need to switch card 1 to card 0 with an .asoundrc file.

Otherwise you have problems with some video/audio file formats not playing,flash drives not automounting,etc..

Hi!

So I need to create a .asoundrc defining the other card to play. I assume your .asoundrc doesn't work for me. Considering that I got these two:

 cat /proc/asound/cards 
 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf0514000 irq 31
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf0510000 irq 32

but what is the required syntax to set the correct card in this file?

So far I tried what I read at gentoo/funtoo alsa page:

nano .asoundrc


pcm.!default {
        type hw
        card 0
}

ctl.!default {
        type hw
        card 1
}

Another thing, I saw at the same page that there is a command to test my audio card output. But it reports that the file or the directory doesn't exist, is it normal?

aplay -D default test.wav
aplay: main:722: audio open error: No such file or directory

lambd0x · November 12, 2015

Got audio working without a .asoundrc in my desktop when using vlc. But not in my firefox.

home · March 21, 2016

I am also having sound problems, so hopefully I can try some of the steps above..since my input shows only Dummy Input.

Alsa, no sound
