Zenith432 Posted April 17, 2017 Share Posted April 17, 2017 (edited) @Slice: Mystery solved. It's got nothing to do with clipOutputSamples or not enough overhead... Here is the bug... With 6 channels, 6 is divisible by 3, yes? The stream buffer size is 256KB. The size of each sample frame is a multiple of 3 - right? So the buffer does not contain a whole number of sample frames. And the code does not set up the DMA right if the buffer is not a whole number of sample frames I reproduced the problem by disabling the Grey pin using NodesToPatch in Info.plist to reduce from 7.1CH to 5.1CH. I get same choppy sound. EDIT: Fixed and tested on 5.1CH - rev 135. Edited April 18, 2017 by Zenith432 Link to comment Share on other sites More sharing options...

Slice Posted April 18, 2017 Author Share Posted April 18, 2017 Yes, it works! Sound is best, no choping. Moreover I took multichannel sound and play it with VLC. I attached 4 speakers and yes, there is a sound from them! surround_test.ac3.zip It's a pity AUDIO-MIDI can't properly test it. 2 Link to comment Share on other sites More sharing options...

Zenith432 Posted April 18, 2017 Share Posted April 18, 2017 QuickTime can also play .ac3 and multichannel .wav if you configure speakers in audio-midi setup to one of the surround configs.iTunes does not want such files in its library and does not play them. Moreover I took multichannel sound and play it with VLC. There are a couple of things that should work now but I can't test HDMI multichannel PCM with > 2 channels. AC3 passthrough on SPDIF or HDMI. In audio-midi setup, the "Encoded digital audio" option is grayed out because the format is not mixable - but there are instructions found in a web search how to set AC3 passthrough up on macOS. Unfortunately, this also needs connecting HDMI port to A/V receiver to test. For HDMI pin that supports hardware mute amp, there's mute control that can be found in System Preferences/Sound or audio-midi setup. In audio-midi setup, the volume control for analog multichannel is still binary. Left controls all left+FC. Right controls all right+LFE. I want to make it possible to control all 6 or 8 channels separately but this needs review and some development of the OSS mixer code. Anyway, it is still possible to set the volume for all channels simultaneously in System Preferences (or the MenuBar) - so at least the most useful volume control works.

Zenith432 Posted April 18, 2017 Share Posted April 18, 2017 It's because your default sound device is set to SPDIF Output. See the icons - speaker icon is default sound output - finder icon is default output for system sound effects - microphone icon is default sound input You can set the defaults with that star icon and dropdown menu at the bottom left or through system preferences/sound no audio front panel (Asus Prime B350M-A) ALC 887 .

mnfesq Posted April 18, 2017 Share Posted April 18, 2017 Are there any settings you can think of that would help reduce the buzzing sound my mid-range and bass speakers make? I can reduce the volume in relation to the tweeters but when I want volume, I get a lot of buzzing as a result. Thanks for any tips anyone can think of.

Zenith432 Posted April 19, 2017 Share Posted April 19, 2017 @chris1111:There are any number of recent changes that could break on old system, such as...- change advertised type of HDMI port from 'spdf' to 'hdmi'. This may crash old System Preferences/Sound prefpane.- setClockIsStable(true), setInputSampleOffset(), setTerminalType().- advertise IOAudioEngineInputChannelLayout or IOAudioEngineOutputChannelLayout. - availability of multichannel engines. @gils83: So I'm left with no useful information that could help diagnose the problem.

Zenith432 Posted April 19, 2017 Share Posted April 19, 2017 Open voodoohda prefpane, select your sound device, and start playing around with the available mixers until you find something usable. My microphones were not working until I did this. The OSS mixer system is not understandable. I'm trying to figure out how control the amp for each channel in 6 or 8-channel sperarately. Are there any settings you can think of that would help reduce the buzzing sound my mid-range and bass speakers make? I can reduce the volume in relation to the tweeters but when I want volume, I get a lot of buzzing as a result. Thanks for any tips anyone can think of. The device is recognized but does not work That part I understood. I mean something useful like getdump. Or check the mixers in prefpane - maybe some volume is all the way off. Stuff like that. Also try lowering 192KHz to 48KHz for a start. 1 Link to comment Share on other sites More sharing options...
