speaker-test fails "Playback open error: -2,No such file or directory"

Background info: I had a working sound, but through the process of trying to bind keys to volume control I got way off track, and broke my sound. I had pulseaudio and pavucontrol which I uninstalled to use pure alsa. Thats where things started.  At this point I cant remember eveything I did. I have changed configs and many other things. please help

Re: speaker-test fails "Playback open error: -2,No such file or directory"

your .asoundrc is set to use hdmi audio for output (card 1), is that what you want ?
if not change it to "card 2" for analog audio or "card 3" for usb audio.

Re: speaker-test fails "Playback open error: -2,No such file or directory"

Please edit your post to add [ code ] tags (click on the BBCode link under the text entry box to learn more).

Then rerun speaker-test without sudo as that's not really expected to work (as it ignores your user's ~/.asoundrc).  Further, don't randomly run commands as root without reason; that's far more likely to create new problems than to solve existing ones.

Finally, you said you removed pulseaudio just to bind keys to changing volume??  You can do that just fine with pulseaudo.  I personally don't much care for pulseaudio - it doesn't suit me - but if you were using it before and happy, why not just reinstall it?

Re: speaker-test fails "Playback open error: -2,No such file or directory"

Also even if you found a working index number, setting up your default like that breaks dmix and will only leave you with a single application able to play sound at a time. The simplest definition to simply change the default device is overriding the defaults node for specific end points, in this case 

defaults.pcm.card 1
defaults.ctl.card 1

but as already stated it's somewhat unlikely you want your HDMI device and you don't have a card 0 where did that disappear to? Can you post 

sudo dmesg | grep snd

as well?

FWIW I agree with the above assertion, if your only issue with the way pulse did things is that you had problems with setting up your keybinds then that's the problem you want to fix and it's trivial to create relevant shortcuts that actually work and play nice with pulse.

I do not know what option of the 3 is the right one for me. I have a set of cheap usb speakers that I use and I also use a set of head phones with the audio jack.  Does my choice of output device make a difference on my  default card choice?

I have tried changing the default card to all 3 options with no success.

Also when I learned that ALSA is include in the kernel my thinking was " why use pulseaudio if I can achieve the same results with the the base linux programs? " As a rule for my machine I try to use the defaults as often as possible as well as the least number of programs to achieve the level of functionality I need. Am I over doing it in this case?

I had read this sentiment on other forums and opted to not use it, as stated above.

I was not happy with my audio configuration, I had sound but no volume control. I just didnt have time to configure it the way I wanted.

Finally I think I have found part of my problem: I do not have a asound.conf

[me@archme ~]$ ls /etc | grep asound.conf
[me@archme ~]

thanks y'all

And are you running speaker-test as your regular user (without sudo)?  Changing the .asoundrc is irrelevant if you run the test as root.

I have edited my post to use speaker-test without sudo. Sorry for the delay, I submitted my reply and then went back to edit it afterwards. please see above.

Yes, the config you define here is static, it will be applied once for a sound producing application and can't be changed to another device unless you stop the stream (... maybe even stopping the entire application depending on implementation) changing the config and restarting the stream.  If that's something you expect to be able to do on the fly - congratulations you've just found out why pulse exists.

Yes, and it should be the only content for a basic test, fwiw dmesg dump looks harmless enough

To be honest I got frustrated with pulseaudio and pavucontrol when setting up keybindings and things simply went awry. Also when I learned that ALSA is include in the kernel my thinking was " why use pulseaudio if I can achieve the same results with the the base linux programs? " As a rule for my machine I try to use the defaults as often as possible as well as the least number of programs to achieve the level of functionality I need. Am I over doing it in this case?

You are free to do whatever, fact of the matter is configuring plain ALSA correctly with multiple devices can be quite involved and you still can't do certain things a "modern" user might take for granted if you're limiting yourself to just ALSA. If you could there would be no reason for pulse to exist. As already mentioned above, probably the biggest thing you'll have is that you can't readjust the device you are playing from on the fly without interruptions so if you intend to switch between the USB speakers and the headphones (connected to the jack on the PC/laptop directly I presume?) then you cannot do that without restarting all your applications that are producing audio with just ALSA.

To provide a counter point to the negative sentiments regarding pulse, I have multiple distinct devices that I regularly switch audio between (usb headset and a speaker setup on the integrated card) switching applications between the two on the fly is absolutely trivial and I've used pulse since it's inception for this usecase.


I was not happy with my audio configuration, I had sound but no volume control. I just didnt have time to configure it the way I wanted.

Chances are that your volume control possibilities with plain ALSA are going to be worse are quite high, e.g. it's often the case that an USB device does not expose a mixer to the operating system and will rely on a software volume, which pulse will set up automatically - and ALSA needs dedicated configuration for.

Finally I think I have found part of my problem: I do not have a asound.conf

[me@archme ~]$ ls /etc | grep asound.conf
[me@archme ~]

As already mentioned as long as you run things as your user then your ~/.asoundrc will be honored and it doesn't strictly matter whether you configure things there or in /etc/asound.conf. This distinction is for whether you want to make a change system wide or user specific.

FWIW we should first establish a baseline to go from, try running (i'm assuming you don't actually want the HDMI device , or are your headphones connected to the monitor's jack out?)

speaker-test -Dhw:2,0 -c2
speaker-test -Dhw:2,1 -c2
speaker-test -Dhw:3 -c2

this should bypass your config and directly play to a device, tell us which one produces noise and should be your preferred default. Also to get some other things out of the way post 

aplay -L
amixer -c1
amixer -c2
amixer -c3

Thank you for the detailed explanation. I will implement pulseaudio once is it confirmed there arent other issues.  speaking of which:

speaker-test -Dhw:3 -c2 output sound successfully out of my usb speakers. yah!

Then there's your problem.  Your asoundrc specifies "card 1" but you want "card 3" as your default if you stick with pure alsa.  Though in some cases these numbers can / will change on reboot - so you should either configure modprobe to load them in the desired order or just not rely on numeric identifiers (both options are elaborated on in the wiki's alsa page).

ok after I updated my .asoundrc to reflect my default device as card 3 and rebooted I now have sound!

contents of .asoundrc

defaults.pcm.card 3
defaults.ctl.card 3

Additionally I will install and configure Pulseaudio!

Thank y'all very much for the help

I didn't intend to "pressure" you into using pulseaudio, but just mention some things you might not be aware of. Also if you do want to set up pulseaudio then all of this is moot, as pulseaudio handles devices in it's own way and you should remove this config and install pulseaudio-alsa instead.

If you do consider this [SOLVED] for your purposes, please mark it as such by editing the topic title in the initial post.
