Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36 Steps to reproduce the problem: 1. plug usb mono speaker : Yamaha pjp-20ur speaker spec: http://www.yamaha.com/products/en/communication/usb_conference_speakerphones/pjp-20ur/?mode=model 2. go to https://webrtc.github.io/samples/src/content/devices/multi/ 3. Local media files: play video and select Yamaha speaker, but no sound If I set Yamaha speaker as system default speaker, selecting default will work but then selecting Yamaha is still no sound. in chromium 53.0.2785.143 select Yamaha speaker, the sound will come out from default speaker; If I set Yamaha speaker as system default speaker, selecting default or selecting Yamaha then sound will come out from Yahama. If I choose other device as default speaker, selecting default or selecting Yamaha will end up from default. What is the expected behavior? sound should come out from Yamaha What went wrong? I'm not sure the issue is about devcie permission or sound quality(e.g. 16bits 48000Hz) Did this work before? No Does this work in other browsers? N/A Chrome version: 50.0.2661.102 Channel: stable OS Version: Windows 8 Flash Version: Shockwave Flash 23.0 r0 issue happened on Windows 8.1 and Windows 10, no problem on Windows 7 no problem on build-in device and usb sound card no problem on Skype or Zoom when they select Yamaha as output It's similar to #623588 (set selected device as default/communications will work but just selece device by sinkId won't) #600736 (device setting to another sound quality will work) In this case, Yamaha default sound quality is 16bits 48000Hz. If I change to 16bits 48000Hz(DVD) then it works. adding --force-wave-audio and setting Yamaha speaker as system default speaker, the sound did come out from Yamaha, but setSinkId won't work since sound always come out from system default speaker Is there any workaround if I don't want to change Yamaha's device setting?

I met the error (as the attach image) when I just open the demo page, and I have no error message when I switch the option to Yamaha PJP-20UR, and the sound still come out from the default device when using Stable version and Canary version. By the way, this problem also happen to Hangouts.

I'm sorry that I can't report more detail debug information. I followed the documents, https://www.chromium.org/developers/how-tos/get-the-code https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md and tried to compile chromium. When I tried to do "ninja -C out/Debug chrome" but met some problem. http://pastebin.com/j5qkShvd

I finally built chrome successfully and here's the error message got from the operation of switching device to Yamaha on sample page. steps: 1. devenv /debugexe out\Default\chrome.exe 2. out\Default\chrome.exe --enable-logging --v=1 3. go to sample page 4. play video and use default 5. switch device to Yamaha 6. pop up a dialog and ask for wait for getusermedia or kill 7. wait for a while, pop up the fatal error window like attach image 8. get the log file

olka@, can you take a look? This is crashing on a Windows-specific DCHECK while reading audio parameters.

AFAK, it looks like a driver issue since it works on Windows 7. As a test, could you modify CoreAudioUtil::GetSharedModeMixFormat (https://cs.chromium.org/chromium/src/media/audio/win/core_audio_util_win.cc?q=core_audi&sq=package:chromium&l=566) // Current code: size_t bytes = sizeof(WAVEFORMATEX) + format_pcmex->Format.cbSize; DCHECK_EQ(bytes, sizeof(WAVEFORMATPCMEX)); memcpy(format, format_pcmex, bytes); // New test code: size_t bytes = sizeof(WAVEFORMATPCMEX) memcpy(format, format_pcmex, bytes); ... and report back if it works for your device.

Lowering priority since it most likely only affects a very specific hardware device.

I can't really do anything about it since I have no win system to play with. henrika@ seems to have some idea of what's going on; also cc-ing grunell@ who does have a win system.

mkidyt: please try the proposal in #9 and report back. Just FYI, the device specification states that the speaker is not supported on Win 8. See http://www.yamaha.com/products/en/communication/usb_conference_speakerphones/pjp-20ur/?mode=model [Windows OS Support] Due to the end of support by Microsoft, we announce to end the support of this product for the following OS. OS：Windows 8, Windows XP, Windows 2000

There is still some issues with the parameters the device reports that Chrome can't handle. Chrome instead switches to using a so called fake device and thats the reason why there is no audio. IMO, the device drivers seems broken somehow but I can't say for sure and it is super hard to make changes just by looking at logfiles. I am unable to guide more at this stage but would need an actual device to do more real work. Must admit that such work (which only affects one device) is nothing we can prioritize right now. Best proposal I have is is if you can play with the audio settings of the device and see if that helps. I don't think that the modified version is a way forward. Or you can contact Yamaha and report the problem and ask for updated drivers given the error message in #9. Or, try another speaker in the mean time.
