Tinkerboard v2.0.0-r15 no sound

[dm6tt]

I installed the latest version on a fresh Tinker_Board-Debian-Stretch-V2.1.16-20200813 image. PiHPSDR was compiled on the tinkerboard, since I the binary thoroug a error due to an old glibc.

Everything is running fine, but the sound does not work. I installed a USB CM108 sound module that works fine directly out of X11.

The log show no error:

Any hint what could be the problem?

I just rebuilt a Tinker Board from scratch and I am not having any problems with audio. Based on your screen dump, did you enable Local Audio by clicking on the checkbox?

Hi John, thanks for the reply. I have two radios running the Hermes protocol. With my Red Pitaya running an older version of Pavels TRX I get no local sound working. This is independent from the 'Local sound' switch. The pitaya has the IP .156 I have a LanIQSDR in my network that can be reached via PiHPSDR as well. Here the sound is working when enabling the 'Local Audio Output switch'. The LanIQSDR has the IP .196 They both use different versions of the protocol.

I will update the pitaya to the latest version and will give you an update here.

Thanks 73, Marcus

Hi John, I tested it again using a red-pitaya with the actual image from pavel red-pitaya-alpine-3.12-armv7-2020062. The sound is not working with this device, but without any problem using the LanIQSDR, Protocol1 v2.4.

Can anyone confirm that sound is working with a red-pitaya in his environmet?

Thanks 73, Marcus

I do not have a red-pitaya so cannot test with it. I do have an ANAN-100D, ANAN-8000DLE, Hermes Lite 2, IquadLabs IQ2, RadioBerry and a bare HPSDR Orion board. All are working with no problem using piHPSDR on the Tinker Board, so I am at a loss as to why this is not working. If the IQ samples are being received and displayed correctly then the audio should be heard provided the correct Local Audio device is selected and the AGC and the AF gain settings are set correctly.

Could you send the log file with the Local Audio disabled and then enabled?

I use an RedPitaya SDR (Stemlab/Hamlab) with piHPSDR with no problems. If the signals are on the spectrum, then the whole audio chain downstream does not depend on the radio. If your radio has no codec, then of course you have to engage "local audio output". It is more likely that you have a problem with your sound cards and/or pulseaudio. Perhaps the pulseaudio daemon is not running?
