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?
