Audio problem with Console
|
jmshaffer_pa
I had the same problem with interruptions in the audio. Changing buffer settings made it more or less frequent but never eliminated it. Changing from VB-Cables to my motherboard's Stereo Mix device made it much more manageable. Changing to Virtual Audio Cable (not VB-Cables) made it almost non-existent. But the thing that absolutely eliminated it was running a device other than the SDRplay! So far I've tried an Airspy and an RX-888 and neither have any audio glitches at all. I have no idea why there's a problem with the SDRplay. The only thing I can think of that sets it apart is that they have their weird API that uses a server process instead of just a device driver. But yet the audio works fine with their own SDRuno software.

i am also using virtual cables here (over half a dozen) ... but i did NOT engage the 250ms buffer setting in console ... works fine maybe he could try that?!? a 100ms buffer filled to 80% is 80ms
... a 250ms buffer filled to 80% is 200ms ... smaller buffer
worked better here (just thinking) dg9bfc sigi Am 03.02.2023 um 09:24 schrieb Simon

Please post the FULL logfile, don't cut out the bits you think are important. There's a lot more information.
Sorry I 'haven't been paying a lot of attention to this thread, busy elsewhere.
ASIO will do nothing, SDR Console uses the Microsoft WASAPI audio drivers (low latency), your problem will be with your chosen VAC.

I have set all input / output to 48KHz (and also 16 bits / 24 bits) but the result here is the same. For G4OGI, I have nothing running on the computer, only SDR-Console. i have also try to put ON ASIO but nothing changed..

Turn off ALL other programs. If that does not solve it you have two clocks that are badly out of timing and nothing can help. {^_^} On 20230201 12:15:37, Nico F4HTN wrote:

Firefox has poor QA recently.
From: main@SDR-Radio.groups.io <main@SDR-Radio.groups.io> on behalf of Nicholas Shaxted via groups.io <nick@...>
..I have found that closing Firefox solves a number of issues I have with SDR-Console. Sometimes if FF is running and I start SDR-C my downline VBCable clients (SpectraVue and SBSpectrum) mis-sample. I run them at 48kHz and clearly the audio is 44.1kHz go into those apps (e.g. smeared traces, stuttering). Check SDR-Console it tells me it is running at 48KHz (32 bits).
The clue in the mis-sampling is audio latency at the bottom od the screen goes above 300ms. And audio starts cracking and stuttering. I normally close FF and restart the radio based apps and it settles down.
So the suggestion is that you might be running another application at 44.1kHz So much simpler to use 48KHz

Set ALL TO 48KC! Resample takes time and may be a reason for buffer over or under runs.. Dg9bfc sigi

I had problems running VB-AUDIO (ASIO Bridge) and SDR-C and scrapped it. I use VB-CABLE from the same source https://vb-audio.com/Cable/index.htm
This works a treat even though the last release seems to have been in 2015

Try a sample rate of 50kHz.

I have tried to put input and output to the same sample rate (I try 44.1KHz and 48KHz) but the problem keep going. For KA1GJU, I have already try with 500KHz bandwidth and the RSP2 is directly connected on the USB port and nothing other with USB on the machine. The CPU load with 500KHz is between 4 and 7%. 73 F4HTN -- - + - + -

Also,
I use the WASAPI driver, SDR# probably uses a different driver.

SDR# may well use 44.1 kHz?

Have you tried operating the RSP2 Pro on a narrower bandwidth? If you are just working NOAA Sat's on VHF FM, you don't need 1 Mhz of bandwidth.
Also, are there other devices plugged into the same USB bus? 73 Kriss KA1GJU |
