5.1 Surround and 1080p Netflix Audials 2022
Hello :)
I bought the upgrade to the new 2022 movie version to finally record surround sound in Netflix as promised. But I don't get satisfying results: Despite recorded files are having 6 sound channels the sound quality is very poor. It sounds somewhat metallic and sometimes sound is cracking or overdriving. Making an individual profile with higher sound bitrate or different encoders etc. doesn't change anything.
Besides most movies won't play (and record) in 1080p but in 960x540 (1080p option activated).
A further but minor issue is the Netflix language selection field. Only the first few options are selectable while the lower options are out of the viewable and reachable window.
All issues are related to the internal player. In Chrome and Edge the movie doesn't even start with 5.1 and 1080p selected.

Ok It starts getting interesting...
I am ripping The Witcher Season 2 right now and look at this. 5.1 ripped with the help of my tutorial. I used Google Chrome. This shouldn't be possible but it is. I am confused right now. So happy Ripping y'all
Edit: My older Rips are actually only 2 Channels in 5.1. Maybe Chrome allowed 5.1 Audio because my new headset has virtual 7.1 support. I also double checked my newer rips and yes these are 6 different Channels and not 6 same.

Enabling 5.1 Audio in Netflix works for me with the built-in Audials feature without the Chrome extension. I also recorded with an ouput format profile with surround sound. MediaInfo shows 6 channels of the resulting recorded file. However, every channel but left and right are silent.
I checked the Log-File and found an interesting ffmpeg parameter setting:
2022-01-02 22:26:54,971 [10756] DEBUG - |Detail| ffmpeg parameters: -f s16le -ac 2 -ar 48000 -i "\\.\pipe\input_20220102_222654_908" -vn -c:a aac -ar 48000 -ac 6 -b:a 320k -c:v libx265 -s 320x240 -preset medium -x265-params crf=17 -r 25.00 -y "C:\Users\XYZ\AppData\Local\Temp\RapidSolution\ConvertFiles\.recording\20220102_222654_775-audio.m4a"
Question: How should it be possible to record 5.1 sound, if Audials sets the number of audio channels of the input source file to 2 (bold -ac 2)?!? Doesn't this parameter mean, that even if the input source file (the recorded 5.1 netflix file) has 5.1 channels, that these are down-mixed again to 2 channels?
If so, is there any way in the command line of a custom profile, to get rid of this input parameter?

As far as my testing goes, you have to use a 5.1 Sound Device to record all 6 channels. I tested it with my stereo headset enabled - I only got stereo sound recording. Then I plugged in a 5.1 external soundcard and used it in the windows settings as the primary output. I recorded again and it recorded all 6 channels. This even works with the internal Audials 2022 Player.

thanks for this hint! IMHO, Audials MUST make a system requirement notice if 5.1 recording is only possible with a 5.1 sound card, otherwise it‘s false advertising!
Therefore, Audials should asap fix this problem in order that every customer, with only a stereo sound card, can record 5.1 sound!Cheers!

Folks!
Meanwhile I also can confirm that 5.1 recording works if you have a 5.1 sound card. I‘ve bought an external 5.1 USB sound card and there it is - 6 channels each with a different signal. Before there were 6 channels recorded but only stereo channels had sound (cf. my previous post).
I‘ve also checked the log-file and my assumption was confirmed: with a stereo card, Audials sets the ffmpeg input parameter -ac 2, which Leads ALWAYS to a 2.0 downmix.
With the 5.1 sound card connected, the parameter was set to -ac 6.Cheers

Hello, I also bought an external sound card.
Yes, there were 6 channels recorded. But as before there is an extreme poor sound quality.
I tried many different settings but always with an awful result.
Can anybody tell me what I did wrong?
(using a windows surface laptop).
Thanks a lot in advance. -
Forget the predefined profiles. They all use AAC as audio codec with 128 kbps, even for ALL 6 channels. Therefore each channel only has 128/6 = 21,3 kbps, which is far too low.
Create your own custom profile and increase the Bitrate to 320 kbps.
Or even better, use the command line argument text field and use a better audio codec.
I‘m using AC3 with 640 kbps, which encodes the source with transparent quality.
The command line arguments for this are:
-c:a ac3 -ac 6 -b:a 640kCheers!

@Faxe36:
yes, sorry I‘ve omitted the necessity that you also need to pass arguments for the used video codec. It depends how you want to encode the video. H.264/H.265 with/without GPU acceleration.
If you want the same settings used by a profile you can do the following:
1. Choose a predefined profile of your choice which uses your preferred video codec
2. Enable Enhanced Logging in the Audials settings
2.1 open that directory3. Start a sample recording
4. Look into the log-file “EncodingBackend.log”
4.1 Search for the term “ffmpeg parameters”5. Look for the one which contains -an in the command line.
6. Copy the video codec specific command line arguments and paste them in your custom profile command line arguments text field followed by the audio codec parameters posted before.
Cheers.

To make it easier, in the following you find my command line arguments.
video codec: HEVC (H.265) Intel iGPU accelerated
preset slow: trade-off between quality/performance; slower == better quality
global_quality 18: ensures perceptual visual video quality equal to source (the value can vary dependent on source material; typically a value between 22 and 18 yields moderate to non-noticeable quality loss)audio codec: ac3
ac 6: 6 channels
bitrate: 640k-c:v hevc_qsv -load_plugin hevc_hw -preset slow -global_quality 18 -c:a ac3 -ac 6 -b:a 640k

@popeye0815 Your method alone didn't work for me, but I installed VB Audio CABLE and configured it to 5.1 sound. Recording with the virtual sound card selected as the primary sound device in windows using the default surround profile worked but sounded bad (because of the low bitrate) but in combination with the parameters determined by your method the results are great :)
