Network connection causing SDS200 to go deaf.

[KevinC]

Glad that you swapped SD cards and that didn't make a difference so that could be ruled out.

Do you have audio out of the scanner speaker?
Is it just the analog, or P25, or both types of channels that have no audio?

Not sure it helps any but I’ve had a Vonets WiF bridge on my 200 for about a month monitoring 7/800 P25 trunked and no lost audio. It’s on 24/7.

All channels (analog and digital) lose audio after >24 hours of continuous operation.

Geez. I hate variations on bugs like this. To date I've never lost any audio on digital systems (initially when I said one of my radios was fine, I hadn't yet realized thats because I had only Digital systems on it). Have we ever seen a trace of UPMan here on RR after Paul O passed? There is a critical mass of people hitting this such that if I had a contact at Uniden that could investigate I'd track them down, but I do not.

Also I VLAN'ed my radios for a month to see if that might help isolate the problem but it did not. It *MAY* have helped reduce the incidence but it's hard to tell since it varies and it certainly didn't eliminate it. I tore down the VLAN yesterday.

I’ll add conventional analog right now and let it run to see what happens.

And just to record it here for everyone, it's a Motorola Type II Smartzone that I consistently lose audio on. P25 Type II Digital is fine for me.

I'm pretty sure it's an issue with just certain SDS200's. Not sure if it's a firmware or hardware issue. It would be great if Uniden Engineering would get involved. The scanner audio should never mute unintentionally.
@JoeBearcat, can you assist in this matter? Thanks.

Here's what I know so far on this issue:

Scanner VOL setting is not the cause.
SD card swap makes no difference.

Analog vs P25 channels: 2 reports analog only, 1 report P25 only, 1 report (yours) both types.
Does not happen with the BCD536HP Wi-Fi rtsp.
VLC test: 2 reports VLC does not cause the issue, 1 report VLC does cause the issue.
Some have more than 1 SDS200 and only a certain scanner does it. Problem stays with a certain scanner after swapping SD cards and programming.
One person stated 'The radio will fail even when running standalone' (not sure if it's the same issue).

Latest available firmware on both my SDS200's

This was me and I was incorrect. I had not yet realized it was analog only that I was losing and the scanner I said was fine was running P25 digital only. Once I added a Moto smartzone analog 800 system in, it too loses audio over time.

 

[KevinC]

Over 24 hours scanning analog conventional also and no loss of audio. This may not help at all, just posting my results.

Over 36 hours and still no loss of audio. Both ProScan and SDS are current versions.

I wonder if anyone else using a WiFI bridge has the problem?

48 hours now and still good. I added a switch (simple Linksys, unmanaged) between the SDS and the Wi-Fi bridge just to see what happens.

24 hours with the switch and still going.

I wonder if it's time for everyone with this issue to post their exact setup (network, what exactly is being scanned, versions of everything, date of SDS manufacture, etc...)?

 

[KevinC]

Or even better, some input from Uniden.

 

[KevinC]

I'm going to guess I either don't have the right combination of variables to make this happen or (if it's HW) my SDS200 doesn't have the issue.

5 days since I added conventional and 3 days since I put the switch between the SDS and Wi-Fi bridge and no loss of audio.

Does this make my 200 more valuable???

Well, yes plus the added value because it was used by a totally awesome moderator. 😊

Can you pm me with the details you have found so far?

I'm wondering if it is a network speed issue. (you may already know the answer to that)

I haven't seen the problem myself. I'm just going by what others are reporting. I don't know anything about the network speed or at least that's something that's not programmed at the application layer in the OSI model. Regardless if it is a network speed problem or not, anything external to the scanner should not allow the scanner speaker to mute.

The SDS I have that experiencing the problem has negotiated a network speed of 100Mbps with my managed switch. The network this device is on is not VLANed and connected to a server with ProScan that is also hardwired (10Gbps). I can force the SDS200 to negotiate to 10Mbps, but that seems excessive.

Worth noting here, we're not seeing ProScan drop the network stream of activity during the muting problem. As mentioned above, the scanner itself no longer produces sound during the problem despite indicating a positive vol number.

Thank goodness that Uniden is involved with these posts. I've been living with this problem for some time now. The audio loss is very frustrating. I've worked with ProScan on this forum and they've been very helpful. It's time for Uniden to get involved. Like most others here, I have the same issues all around and have provided test data here on the forum. I am available to work with Uniden to help fix this issue. There needs to be some log data available in the scanner that can help. Thank you!

I will keep a close eye on this thread. It sounds like an issue that only affects some units which will be pretty hard to track down.

I wonder if someone can test changing the IP on the scanners involved (especially those who have two or more units and only one with the issue). We will be fine as long as the thread does not become a debate.

 

[r6daddy]

I can certainly try a different IP address. Currently, I have an address reserved for the SDS 200. Is there a log file in the scanner that can be retrieved? Would be the easiest attempt to troubleshoot. You can review the many conversations and attempts to resolve this issue. Too much time has passed without a resolution for this high end scanner. ProScan has taken much flak for this issue that may be a scanner hardware problem. Not fair for him/them. Very disappointing. Please help. We're all anxiously waiting for a resolution.

The problem is that no definitive cause has been found yet. This is one of those 'very hard to fix' issues. If we can get close to a cause, or someone that solves the issue, that will give the engineers something to go on. I would very much like to see it solved. It seems to only happen when there is LAN communications.

I will check to see if the log will be able to show anything. Can you reproduce the issue consistently and are you willing to test?
