Post-F1 keypress crash

[KnuckleBob]

I get the following output after connecting to the server and hitting F1, any ideas?

I get a very similar error in the same condition. what can i do about it?

[KnuckleBob]

After some more investigation, this is related to ALSA and not having the ability to directly select the proper sound capture card or output card. By creating a local ~/.asoundrc file, I've been able to get past the F1 crash to transmit sound (and other parties can hear me), but now I get a crash when someone else in the same channel transmits back to me.

My issue stems from the fact that I have >1 sound devices in the machine and need to use one for sound output and one for sound input. I've not yet made sense of the spaghetti that is ALSA to get both TX and RX working w/o a crash.

[KnuckleBob]

Okay, added an .asoundrc that seems to stop the crashing when either F1 is hit or the other side transmits sound but I need to do some more testing later today.

My configuration:

Sound output device: card 0 = internal sound card that only has output

Sound input device card 0 = External USB mic that has only input capabilities

}

[KnuckleBob]

The above .asoundrc ended up working around the crash bug for me. It in effect binds two separate devices into a single one:

• Record from device hw:1,0 (USB mic)
• Play through device hw:0,0 (built-in sound card)

Thank you very much! I will try on mine today. I have an unusual hardware configuration which involves a Bluetooth headset over Pulseaudio following this guide: http://youness.net/raspberry-pi/bluetooth-headset-raspberry-pi-3-ad2p-hsp. I assume this should work in principle with barnard, right?
