Muted icon but audio is playing (after loss of sync) #158

Open andimik opened 2 months ago

andimik commented 2 months ago

Described in https://www.rundfunkforum.de/viewtopic.php?p=1772782#p1772782

Although the main reason might be a loss of sync Qirx shall not play audio when it is muted.

The icon still remains the same (no sound icon), BTW.

Please describe your problem here in this thread, as for readability of the thread it is much more useful to have the problem description here, and not having to read first in another forum. In addition, not every user reading here understands German.

Thanks.

Einen schönen guten Abend Clem,

in such a case, Qirx will forget that MUTE has been pressed before and will play audio.

I can reproduce it.

Sometimes the icon stays on mute on like in the screenshot, please have a look at the audio mixer.

When I press the mute icon (from mute to not mute), it will still play the audio, and the output will change to 

Audio Mute off
andimik commented 2 months ago

You could try this:

a) mute a station b) change FFT lenght to a very high value c) sync loss d) audio plays

softsyst commented 2 months ago

Andreas,

Here on my machine, I am not able to reproduce the behavior you are describing. I do not get a sync loss on selecting a high FFT length. However, a sync loss is easily forced if the gain is reduced or (as I do it here) on a RSP when a high LNA state is selected, which is essentially the same. Here, when muted, after re-sync after a sync loss the mute icon is off, the audio plays.

This is the intended behavior. In this way you can easily check that an unsync happened, without the necessity to stay at the receiver. Just let it play and mute. If you leave it this way, as soon as the audio starts playing you know that a sync loss had happened. This was particularly useful when the rtl_tcp.exe lost samples. Only after @old-dab's research on this, his rtlsdr was stable enough for long-time playing of DAB without losing samples. The RSPs never had this problem.

So, if that was your problem, all works as intended.

I'm glad you could reproduce it.
