Could you run the pa-info script (hopefully it's packaged in your distribution) when the stream is playing fine vs. when it's not playing fine? The idea is to see if any mixer controls or any of the stream/sink volumes have actually changed when this happens, or if something else is going on lower down in the hardware.<br> <br> -- Arun<br> _______________________________________________<br> pulseaudio-discuss mailing list<br> <a href="mailto:pulseaudio-discuss@lists.freedesktop.org" target="_blank">pulseaudio-discuss@lists.freedesktop.org</a><br> <a href="https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a><br> </blockquote></div> </blockquote></div> _______________________________________________<br> pulseaudio-discuss mailing list<br> <a href="mailto:pulseaudio-discuss@lists.freedesktop.org" target="_blank">pulseaudio-discuss@lists.freedesktop.org</a><br> <a href="https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a><br> </blockquote></div><div><br></div> </div> _______________________________________________<br> pulseaudio-discuss mailing list<br> <a href="mailto:pulseaudio-discuss@lists.freedesktop.org" target="_blank">pulseaudio-discuss@lists.freedesktop.org</a><br> <a href="https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a><br> </blockquote></div>
