Re: possible DRAWS hardware failure.
I ran your suggested procedures and I am still where I was when I
started. When I run FLDIGI, after doing all the prerequisites for
shutting down DIREWOLF and and running ./ax25-stop , I still
cannot select a sound card from the fldigi audio setup menu. To
select the the codec from the fldigi audio set up I must have
#dtparam=audio=on commented out in the config.txt file. With
dtparam=audio=on commented out with the # symbol I can then select
urdc: - (hw:0,0) , not urdc: - (hw:0,1) for capture and
urdc:-(hw:0,0) for playback. This result is what you said
enumerates with dtparm=audio=on commented out, only hw 0,0 will
When following the new draw "getting started doc "DRAWS Raspberry
PI image" from the wiki and run "aplay-l I" do not get the same
results shown in the example of the doc.
This what I see:
I have tried re formatting the micro sd card, changing sd cards, re burning the image, changing the RPi 3 B+ to a different RPi B+, powering the RPi/DRAWS board from 12 volt supply. I am out of ideas and because of the anomaly in the results from aplay -l I think the problem it is a hardware failure of the DRAWS Board.
If you have any suggestions I am ready to try them.
Best regards and happy New Year,

Joe, Thanks for all the information.I have been successful in verifying the core operation of Beta 6 and have Direwolf/YAAC running without issue on port 0. I also have FLDIGI running on port 0 (left hand port on the draws board) without a problem but had to deviate from the information in DRAWS_CONFIG.md. The directions in the verify document tell us to remove the # from dtparm=audio=on to "Test analog audio" . I do that by removing the # in the config.txt file for the Rpi and the test runs and I get the results indicated. The same is true for "TEST OF HDMI AUDIO" . By the way there is a minor error in the information the beta 6 release doesn't have a file named "silence.wav" in $ /usr/share/xastir/sounds.Yes I see that. I'll fix it. For now just copy it from n7nix/xastir/silence.wav to the /usr/share/xastir/silence.wavHere is the question. When I complete the verify core test and shutdown --ax25You need to run a script in your local bin called. ax25-stopand then start FLDIGi and try to configure the sound card FLDIGI fails and shuts down.Try this. You should see the process id of direwolf the first time you run pidof and not the second time. cd cd bin sudo su pidof direwolf ./ax25-stop pidof direwolf Now run fldigiIn fldigi under the choices in the audio selection menu there is no udrc audio choice available.I just tried it & Fldigi enumerates: udrc: -(hw:1,0) without the enabled RPi sound device the udrc will enumerate like this: udrc: -(hw:0,0) I have a feeling you are not shutting down direwolf. The next image will have direwolf unloaded by default.IF I go back to CONFIG.TXT and comment out, put the # in, for the line dtparam=audio=on, reboot, start FLDIGI I can then select the udrc 0 port and complete the configuration of fldigi without issue and fldigi runs just fine. Am I overlooking something in your instructions? Or are we to comment out the dtparam=audio=on in the config.txt of the RPiThere should be no problem enabling the BCM2835 RPi sound device. I use it with Xastir for the sound alerts.I am making some progress with WSTX I can receive and decode but not transmit yet. I need to recheck the cable I made that goes from the 6pin mini din of the draws board to the 13 pin Din of my TS 590. Thanks, K3JV Joe
