Sound stopped working -

[Bob Goodwin]

Sound stopped working after I tried a USB Sound Adapter, which
        only lit its indicator leds.

Normally the following should produce sound from the loudspeaker.
        [root@box6 bobg]# aplay /usr/share/sounds/purple/login.wav
        ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
        aplay: main:660: audio open error: Device or resource busy

It does not, and no sound shows on the PAVC input or output
        bars. I'm not certain of how signal moves through the sound
        circuit but it looks like it doesn't get from PA to ALSA input?

I can feed a signal into the sound input jack and produce normal
        indications on the PAVC display and sound at the loudspeaker.

Apparently plugging in that USB "sound adapter" switched
        something in the logic. Rebooting has not changed things? Is
        there a default conig. file somewhere?

I've tried everything I can think of via the alsamixer display
        settings.

Everything did work normally before this.

Also, it would be helpful if there was a way to generate a
        continuous tone or keep aplay looping continuously when messing
        with cables under the desk, etc. I have not been able to find
        anything to do that.

Suggestions wanted, what do I do next?

Bob

Good, this works but how to stop once started? All I found is
        Ctrl Alt Backspace which is inconvenient.

As for the original problem I now suspect hardware, perhaps the
        headphone jack on the front panel but that's a work in "progress."

Thanks,

Bob

Just kill the terminal that it's running in.  As long as you haven't 
started it with "&" it will die when the terminal dies.

Ok, that will work for me.

If aplay is working then something is probably screwed up in your
PulseAudio configuration.

Please post the full output of "pacmd info", which dumps Pulse's
configuration.

Is "pacmd info" a command? I cant seem to do anything with it,
        "locate" shows nothing?

I need to look at the headphone jack circuit, it causes the
        output on the back panel to be switched on/off and I am
        suspecting something intermittent there?

rpm -q pulseaudio-utils

if not there:
yum install pulseaudio-utils

Below is the part that lists devices that output sounds.  It's only

With some devices you can switch the headphone jack/speakers using
`pacmd set-sink-port 0 <port>`, where <port> is one of the ports
listed below.  Unfortunately, it doesn't look like you can do that
with your card.  :-(

I suppose there's a small chance that the amplifier business is
causing problems, so it ` pacmd set-sink-port 0
'analog-output;output-amplifier-off' ` might be worth a shot, but try
the set-card-profile thing explained below first.

In my experience, having the active profile set as anything with
"input" in it results in no sound, though I haven't the slightest idea
why.

Try `pacmd set-card-profile 0 output:analog-stereo`.

Below would list all the apps feeding or eating sound from PulseAudio
at the time you ran the command, if there were any.  If you play some
sound, you can see the application playing it listed here and what
audio device it's using.  Might be useful if you attempt to use the
USB card again.

Sorry I can't be of more help.  If any of the above doesn't work,
you're probably right about it being a hardware issue.  Everything
else in PA-land looks fine.

No, that's a lot of help, it gives me more insight into how to
        troubleshoot the problem.

Mainly I need sound to announce incoming e-mail/text messages. I
        filter them to voice announcements, etc.

The trouble arose with a program [from yum] fldigi which
        interconnects the computer with the HF radio providing phase
        shift keying for transmit and receive. PA enables controlling
        the levels, the signaling is via audio frequencies, and normally
        it works well. I'm running out of jacks so have been using the
        front panel audio output jack and have been pulling the plug
        when I wanted to use the radio system, perhaps resulting in a
        failure there ... However the problem seemed to happen after I
        plugged in that USB sound gadget to see if I could get an extra
        jack there, after which I began to have audio problems.

Anyway armed with new information I will have another go at it
        later.

Thanks much,

Bob

You may want to check the default output in PA. It sounds like it is
getting changed when you plug in the USB sound device. This would be
especially true if you booted with the USB sound device, and later
removed it.

I missed the start of this thread, so I do not know if your sound
card is being detected as card 0, or card 1. (aplay -L) If it is
card one, then the USB sound device is probably being dected as card 0.

One nice thing about PA is that you can select where the sound
output of a specific program goes. You can have the system sounds go
to your sound card, and HF radio going to the USB sound card.

I hope this helps.
