Loosing audio sync over some time of watching TV

zzachm · June 24, 2018 at 8:40 AM

Hi, I would need some help. I have observed that the longer I watch TV the more sync problem I have. No matter if it's an encrypted channel or FTA.

Formuler S Turbo: 1.6.0, audio codecs installed, HDMI output = Auto, Digital Sound Bypass = Enabled and Disabled (both tested), Sound Type = Stereo, Resolution tested: 720p/50Hz, 1080i/50Hz, 1080p/50Hz, Audio tested (yellow button) = AC3 (oryginal) and auto

+ oryginal cable from the formuler set

+ TV Panasonic TX-L42ET60

I've been using this TV with Ferguson Ariva 100e HD for years without any problem.

Audio gets synced:

- while Formuler is switched off and on again (standby or full off)

- while changing audio in TV to analog (disabled) and digital (enabled) again

You can see the problem watching lips of speakers even after 45 min of usage!

Please provide any help. This issue drives me nuts!

1. You speak about DVB or IPTV (MYTVOnline) streams?

2. Did you set any lip-sync values and filters on your tv for this hdmi port? On some TV`s you can save individual settings for each HDMI port.

3. Tried with setting only LPCM under Android -> Audio? Please test directly Box->TV (without avr receiver or similar).

Hi SAM, thanks for picking up this topic.

1) DVB - Satelite Antenna
2) I have no other settings in TV than DIGITAL (HDMI-HDMI) or ANALOG (DVI-HDMI). Only DIGITAL works for me.
3) Tried also to use LPCM. Same issue. Box is connected directly to TV

I've tried also reset to default (twice). No changes there. I can see that sync is lost in linear way. It starts in sync and it get's wore over the time.

zzachm · June 25, 2018 at 4:00 PM

I have also set 'GAME' mode in TV to disable any image postprocessing. Still it does not work for me.
What's funny is that I have unplugged Ariva and plugged Formuler. Then I have discovered this issue. After that I've started to play with box and TV. Believe be I've tried lots of configs over last 3 days.

SAM · June 25, 2018 at 5:18 PM Official Post

I belive you 100% but lip-sync delay is more present on iptv and rar on dvb. I would suggest following.

Tomorrow should come out new firmware for S Series. Install this when it`s out and new MOL, after install do factory reset and set the box again.

Maybe this solves your problem at once.

zzachm · June 25, 2018 at 6:19 PM

Great, looking forward to a new FW
I'll keep you updated after FW is installed and tested.

Simply_Sasha · June 25, 2018 at 9:21 PM

I have the same problem and hope new FW wil be a solution.

Simply_Sasha · June 26, 2018 at 11:36 AM

Unfortunately, the problem remained.

I did factory reset, installed new FW (1.6.11-к15210), did factory reset again.

There is a loss of synchronization when viewing the DVB - Satelite Antenna.

Box is connected directly to TV.

I tried to change setting under Android -> Audio, LPCM and auto, no difference.

Synchronization helps to change the resolution, but not for long.

SAM · June 26, 2018 at 1:49 PM Official Post

Ok, let us test this issue more with latest fw and collect more data, problem should be reproducible.

1. Which satellites do you use ( Sasha and zzachm) ?

2. Lip sync issue only on one channel, few channels all channels, one satellite, all satellite? Please monitor this and give feedback.

3. Area you live etc.

Detailed info are always welcome.

Simply_Sasha · June 26, 2018 at 1:56 PM

1. Only 36.0E Eutelsat 36A/36B

2. Lip sync issue on different channels.

3. Russia, Moscow

zzachm · June 26, 2018 at 2:00 PM

Hi SAM,
1. Hotbird 13E only, Single antenna/converter, no diseqc
2. It applies to all channels
3. Poland, Wroclaw (51°06′00″N, 17°01′59″E)

Direct connection BOX<>TV

Sound set in BOX AC3 or auto - no difference

HDMI Auto/LPCM/RAW - no difference

MYTVOnline installed or not - no difference

audio codecs installed

is there any way to collect logs from BOX and send it out for review?

SAM · June 26, 2018 at 2:04 PM Official Post

Could you please backup your Channel settings/list and do new channel scan for Eutelsat 36 E? It`s important to check after scan all problematic channels without any edit trough C-Tech editor or similar. RAW test, scan and check.

Please same also for 13E. Thank you.

zzachm · June 26, 2018 at 2:25 PM

Sure thing. I'll export them and post a link to it in the evening.

One question. Should I do:

- Factory Reset > Update to 1.6.11 > Factory Reset

or just

- Update to 1.6.11 > Factory Reset

SAM · Update to 1.6.11 > Factory Reset

Update to 1.6.11 > Factory Reset

Checked with clean channels without editing after factory reset (only set up wi-fi, installed XcamClient3, not installed audio codec) - the problem remained.

not installed audio codec

Audio codec is must have, please install.

Simply_Sasha · June 26, 2018 at 5:26 PM

I did it and also i changed PQSetting, now i test this with default audio codec settings.

zzachm · June 26, 2018 at 10:08 PM

Looks like it works for me. Here's what I did:

1. Reset to default using red button on 1.6.0*

2. Update to 1.6.11

3. Reset to default using menu

4. Reset to default using red button on 1.6.11*

5. MyTVOnline installation

6. Channels search

*)

AC power OFF > AC power ON

Repeatedly press the Red key until the front LED flashes alternating RED/GREEN

Press 1 on the RCU to factory reset the device

Now I'm going to set WiFi and enable TimeShift. Hope it will not break anything.

Simply_Sasha · June 26, 2018 at 10:35 PM

I'm afraid to jinx, but so far there is no lip sync issue. I just using factory reset (no red button).

I think (and i hope), new channel scan is solution.

Simply_Sasha · June 27, 2018 at 10:40 AM

Unfortunately, after sorting the channels from the remote, the problem reappeared.

zzachm · June 27, 2018 at 10:50 AM

I can confirm. I've changed 2 channels position using RCU and spotted the same.

EDIT:

Using a shared .nsvc file with channels already sorted by another Formuler S Turbo user causes the same issue.

Looks like a 'scan and do not touch'

SAM · June 27, 2018 at 2:05 PM Official Post

Very interesting. What happens when you import the fresh channel list and edit with c-tech editor?

zzachm

Could you please upload your 13° list as attachment, would like to import and test the channels? Please tell me also which channels (by name and slot nb.) are affected.

zzachm · June 27, 2018 at 2:20 PM

Sure, I'll upload them after I get back from work.

Maybe I have one idea... I saw the '.nsvc file with channels already sorted by another Formuler S Turbo user' in Clarke Tech Editor Studio. It has diseqc config different than my settings. Still I have no idea if uploading such a file changes also diseq settings in my box and if it can cause problems if it does not .

Moreover I will check my own .nsvc files before and after RCU manipulation regarding diseqc settings.

SAM · June 27, 2018 at 2:28 PM Official Post

Diseqc settings must be always checked and changed individual, sometimes they match and in many cases not.

zzachm · June 27, 2018 at 2:44 PM

Sure, I've just started wondering if channel manipulation using RCU does not break Diseqc settings IN .nsvc inside the box.
Why? Beacause I saw that the .nsvc file from another guy that also causes problems has different disqc settings than mine.
I don't know how box handles .nsvc file but, just maybe, it leaves my own system diseqc settings and applies channels settings with a different diseqc settings than system's one. Maybe this mismatch can cause problems.

It's just a wild guess. We'll see in the evening

In my case i only scan channels and just sort them by using only remote control unit, without any editors and any files from other box.

zzachm · June 27, 2018 at 5:26 PM

My lists here:

https://drive.google.com/open?id=1EOQHe…4oxpusNIChTtnOZ

Channels moved

TVP 1 to position 1

TVP 2 to position 2

Additional question:

Simply_Sasha - Do you use any disc/flash USB for Timeshift?

If you upload settings from someone else, there is not only channel list, diseqc settings are also included from him. If the diseqc not match you will not have any signal on this Satellite. I see the problem in the list, if you say that raw list works fine and changed not, we should do research in this area.

This are already edited channel lists with lip sync issue and tvp1-2 are the channels, right?

Can someone, edit the good working raw list with c-tech editor and check again? Please don`t use the box to change anything, we need just more infos.

zzachm · June 27, 2018 at 7:10 PM

Another Factory Reset, another clean list without a single touch and again sync issue. Time needed: 1h 25min.

Enough is enough! This box goes back to the seller! It just don't work.

zzachm · June 27, 2018 at 7:42 PM

If a resolution change cleares (for a while) sync problem it can't be a list issue.

What values do you have under:

1) Menu > Android > Settings > Advance options > Video color space & HDMI deep color

2) Menu > Android > Settings > Advance options > TV HDR Mode

My TV is old but I had HDR 10 set in TV HDR Mode. Just changed to SDR and testing.

festo · June 27, 2018 at 8:20 PM

zzachm, do you have Digital Sound Bypass (AC3) in the A / V settings? try turning it off. and yet, your receiver reproduces high quality video in 60fps, not YouTube, and media files from the receiver or DVB channel?

Simply_Sasha · June 27, 2018 at 8:41 PM

In my settings Digital Sound Bypass (AC3) is turning off.

zzachm · June 27, 2018 at 9:12 PM

The same as Sasha

Now I'm checking Video color space & HDMI deep color = RGB and TV HDR Mode = SDRprogress

EDIT:

No progress

festo · June 27, 2018 at 9:58 PM

zzachm, Simply_Sasha please check if you have problems with video playback and DVB channels with 60 fps? not YouTube (!)

Simply_Sasha · June 27, 2018 at 10:15 PM

I use only DVB 1080p 60Hz (my tv only fullHD).

What do you mean 60fps?

When you lose sync, what happens when you turn the TV off and On?

Does the A/V get synced again?

YES

It also get's synchronized when:

- Formuler is swithed off-> on

- Resolution is changed

Thanks for reporting back.

This is the first time I have heard of this issue with S-series devices.

It is very difficult to test our device for all Satellites/Countries/TVs that are out there.

Appreciate your feedback and patience in advance.

In order to isolate the problem, please do the following and report back:

Connect your S-series Formuler device to another TV and test again using the same conditions/settings
- Although you have another set that doesn't display the sync issue, sometimes the TV is the cause of the issue.
Connect a USB or network drive to your Formuler S-series device and Record the channel until you experience the sync issue. Continue to record 5-10 minutes more after the audio and video drifts out of sync.
- Playback the recorded file on your S-series device and check for a/v sync
- Playback the recorded file on your PC and check for a/v sync
