Permission issue?

[nik]

I made a fresh install with Raspbian Jessie and followed the setup-guide. Kernel is now 4.9.24-v7+. (rpi3)

Test without .asoundrc:
Logged in via ssh as user, command "speaker-test -c8" work, get sound.

But i get an error, when .asoundrc is added:
ALSA lib pcm_hw.c:1741:(_snd_pcm_hw_open) Unknown field slave
It works with command "sudo speaker-test -c8"

Same behavior with /etc/asound.conf instead of .asoundrc.
User is member of the audio-group.

Suggestions?

oh ok, sounds like a .asoundrc bug, but can't be sure.

Can I please ask how you generated the .asoundrc file ? Do I need to fix a bug my end ? Can you please post your .asoundrc file here so I can check it ?

I have checked the .asoundrc file from the automated setup system with command line applications (aplay and arecord) for 8 channels and less of audio. I have also checked the .asoundrc file with the application audacity running only stereo. Some may not know that audacity is a GUI based audio recording and editing software. Audacity isn't as full fledged as some DAW softwares, but good for some use cases.

thanks

Hi Matt,

here the .asoundrc

Code: Select all

pcm.!default {
#       type hw
#       card 0
        type hw
        slave.pcm "anyChannelCount"
}

ctl.!default {
        type hw
        card 0
}

pcm.anyChannelCount {
    type route
    slave.pcm "hw:0"
    slave.channels 8;
    ttable {
           0.0 1
           1.1 1
           2.2 1
           3.3 1
           4.4 1
           5.5 1
           6.6 1
           7.7 1
    }
}

ctl.anyChannelCount {
    type hw;
    card 0;
}

Taking from your setup-guide, generated with copy and paste in leafpad on my linux-notebook and moved via ssh (mc).
ls -l -a on the rpi:
-rw-r--r-- 1 falter falter 437 Apr 27 20:52 .asoundrc

Tested with aplay, speaker-test and trying moc

e.g.:

falter@raspberrypi:~ $ mocp
Running the server...
Trying JACK...
Trying ALSA...
ALSA lib pcm_hw.c:1741:(_snd_pcm_hw_open) Unknown field slave
Trying OSS...
FATAL_ERROR: No valid sound driver!
FATAL_ERROR: Server exited!

brutefir also doesn't work with .asoundrc.

Without .asoundrc is all that no problem and works flawlessly.

Yep ok, my bug.

In your .asoundrc file, please change

type hw

to

type plug

That should fix the problem

[nik]

That should fix the problem

Yes, it works!

thanks

Can you tell me, does the problem return when you reboot ?

Thanks

Hi Matt,

the problem is never returned. (I did serveral reboots in the meantime, use new .asoundrc)

With my installation (rpi3, 4.9.27-v7+) the changes to .asoundrc do not survive reboot. Furthermore, pressing "Make Default" in "Audio Device Settings" revokes the changes made in .asoundrc.

Is there a system wide configuration ?
/etc/asound.conf
Can you copy the .asoundrc file to /etc/asound.conf ?

Does that change anything ?
thanks
Matt
