Re: Digipeater build.... not hearing packets
Run alsamixer in a terminal, hit F6 key, move down to the soundcard you want, hit Enter.? Hit F5 key to show all settings.? The "Speaker" slider is obvious, audio-out.? Use up/down arrows keys to increase/decrease.? The next slider, "Mic", should be muted or at zero; it's for playback thru speakers what it hears on the mic-in, so that's no good for digital modes.? The next slider, "Capture, Mic", is audio-in from the radio, make sure it isn't muted and has some level indicated.? The last slider,"Auto Gain Control" should be muted.? Muting is toggled on/ff using the "M" key.? If a slider is muted, you'll see two "MM"s.? When finished, hit Escape to exit alsamixer.? The settings are saved automatically if you're using a Raspberry.? In other Linux flavors, run "sudo alsactl store" in a terminal to save the alsamixer settings.

Re: Digipeater build.... not hearing packets
Yep, check Alsmixer settings.? Maybe the capture input is actually muted.

Re: Digipeater build.... not hearing packets
Yes.. I'm pretty sure you have incorrect mixer level
settings.

Here's my to-date testing.? This will likely leave
open some of Rob's points, but it's as far as I've gotten.
- Headset (with 2.5mm and 3.5mm jacks) plugged directly into
radio; hear packets.
- I hooked up my audio cable (two-pin 2.5/3.5mm jack) from my
Anytone to my laptop (with APRSISCE32 and UZ7HO installed) and
it receives and decodes normally.
- I added splitter to end of that cable and plugged one jack
into USB sound card mic side; everything worked normally.
- I booted up Direwolf.? Had both ends of splitter into USB
sound card.? Same as before--show up on aprs.fi but not
receiving packages.? USB sound card is blinking away as it
does when receiving packets on laptop.
Let me know if I left off a test that might help diagnose.? I
haven't had a chance to look up threads here on AT/Wouxun issues,
but is it time for me to head down the Alsamixer path?? Is there
any chance a line of code is wrong?

Re: Digipeater build.... not hearing packets
Sorry if this was already mentioned. But ensure that "Auto Gain Control" is disabled on your device through the alsamixer tool.?
Open alsamixer
Press F6 to select your sound device
Press F5 to show all devices
Select "Auto Gain Control" and press m so that the Item entry on the top left shows [Off] next to Auto Gain Control.
You may need to turn the mic gain up or down after that.
Hope that helps,

Thanks, John. You're right. That's a much easier solution. Worked like a charm.

Re: ADEVICE with USB on Raspberry Pi
Win some, lose some!
The advice to remove PulseAudio has been superseded and not
considered necessary anymore, but not having it certainly rules out
Pulse grabbing anything!!

Re: ADEVICE with USB on Raspberry Pi
Could it be that PulseAudio is grabbing the audio device in a random
manner. It happened here so I blocked the affected devices from
PulseAudio with a udev entry.
Create
/etc/udev/rules.d/89-pulseaudio.rules
use my content below as the starting point, suitably modified to fit
your environment ...
Sample content ......
/etc/udev/rules.d/89-pulseaudio.rules
#Ignore SB Play in pulse audio. Required by Direwolf
ATTRS{idVendor}=="041e", ATTRS{idProduct}=="30d3",
ENV{PULSE_IGNORE}="1"
#Ignore CM108 in pulse audio. Required by Direwolf
ATTRS{idVendor}=="0d8c", ATTRS{idProduct}=="013c",
ENV{PULSE_IGNORE}="1"
Reboot or restart PulseAudio to activate.

Re: ADEVICE with USB on Raspberry Pi
since aplay -l and arecord -l show your USB sound card as "card 3:" I would just go with
???? ADEVICE plughw:3,0
If youy are plugging and unplugging USB sound devices, then I would worry about the other stuff.

Re: Digipeater build.... not hearing packets
That isn't the question.? You don't use the HT speaker, so you need to know audio is coming through the cables you are adding.
There are many times these special cables don't make good contact or make "double contact" and cause the audio to not actually go through.
The pictures in the article you mention shows:
?? a) radio
?? b) cable that connects to the radio
?? c) Y-cable from that cable to the sound card mic input (radio speaker output) and headphone (radio mic)
?? d) USB sound card
So, troubleshooting RX would mean you have to follow the audio from radio to USB sound card.
??? Do you have a way of connecting headphones or speakers to the radio and cable that directly connects to the radio. Audio chain a) and b).
??????? This is typically a TRRS type connection, unless you cable has 2 ports (mic and speaker)
??? If there is audio there, including static, add the next cable [ audio chain a), b), and c) ]
??????? Is there audio on the cable that goes to the USB sound card Mic input.
?? If there is and you have those connections correct (as mentioned above), then
??????? the most likely issue for receive would be the Mic settings - use alsamixer to adjust the settings there.
???

Re: Digipeater build.... not hearing packets
Rob, do you mean Rx of packets/beacons or Tx (digi)?? Nothing on the latter and, yes, when I removed the audio cable from the HT, I hear the packets come through (and when using the AT878, I see the beacons being displayed on the screen).

Re: Digipeater build.... not hearing packets
That's wasn't expected to fix anything, just get you caught up with the latest features.
Have you verified there is sound coming out of the radio through the plug?
