[QUOTE="rlevis, post: 1290605, member: 81718"] I have a similar issue occasionally with MP and a Marantz NR1711 AVR. When MP is not playing video, the AVR status shows the audio source as "Multi Channel PCM In" or similar. When starting a video it should change to Dolby Surround or whatever audio format the video contains. I find that after waking the PC from sleep sometimes, you can hear the MP sound effects from moving within a menu but when starting a video, it is silent because the AVR hasn't switched to Dolby and still shows Multi Channel PCM as the audio source. Sometimes stopping and restarting the video resolves it, but sometimes I have to restart MP or reboot the PC to fix it. I have always assumed a problem with the AVR but I'm not sure since actions are required on the PC. The PC is using built-in AMD graphics. Luckily a reboot only take 15 seconds or so as it's a fast NVMe SSD. Perhaps check your AVR audio source and see if that's what's happening. [/QUOTE]
