Title: Using WASAPI with MC14: Getting Directshow Failed to play error
Post by: rayden on September 06, 2009, 06:51:07 am

Hello everyone,

After getting no luck with ASIO drivers for my external yellowtec PUC2 soundcard I am trying to switch to WASAPI. However after enabling that in the output mode when I try to play an audio file (WAV or FLAC) I keep on getting the error mentioned above and MC is complaining that it can't find Directshow filter.

I have already gone through FAQs and Wiki on the forum and have installed AC3 filter and file. I also tried CCCP but nothing seems to work. It seems like the MC can't make the connection to the filter.

I have also gone in tools > options > file types and tried both JRiver audio playback methods (changing from automatic) but still no luck. I have also tried Video options in playback tab although not sure if they would help anything.

With Direct Sound it seems to work fine.

I am using Vista 32-bit with SP-2.

Please help as I am running short of options :(

Thanks

WASAPI shouldn't need DirectShow.  Check Tools/Options/Filetype.  Playback should be "Automatic".

Make sure you don't have other filetypes in the list you're trying to play.

Make sure you don't have another player using WASAPI in "exclusive" mode.

I put the playback to the default setting of automatic and I still receive the same error message.

I tried with just one wav file in the play list and it still does not work.

I only had WASAPI enabled in FOOBAR but I have put it back to DS. Is it possible the Windows Media Player somehow may have it enabled. I ask because I did not configure it but with MS products you never know if they have some "automatic connection"

Playing to the wrong sound device?

In the output mode settings there is only one device (PUC2) which is the right one for my soundcard other than default.

Ok made some progress. I needed to uncheck the "exclusive control" setting and also needed to hard code the bits to 24 with 48000 and channel to 2 in MC output format and now it works :)

Don't know why it would cause an issue though as there is no other application at least I am aware of using the soundcard.

BTW for "pops and clicks" can one play with buffering? Is there any recommendations on that one?

Also ASIO sounded a bit smoother compared to WASAPI. Anyone else had the same feeling playing between the two with the same sound card or DAC?

Thanks,
