Solved: Sound form NAS is breaking up via WiFi connection
#1
Hi,

I updated to 4.3, sound is breaking up (choppy) form NAS source via WiFi network.
I checked and confirmed there was no problem like this on v4.2.

This problem doesn't occur in case of  internal SD-Card playback, and web-radio streaming.

Thanks.

- What model Pi and network adapter are u using?
- Samba or NFS?
- What does ping <to your Router ip address> show?

Hi, thanks for reply.
Pls refer the followings...

- 3B+, and Zero W, on-board WiFi.
- I use Samba.
- Ping (to WiFi AP : 10.0.1.1) shows as below;

The regularly occurring 25-30ms ping times could be an indication of an issue if they roughly correlate to the audio glitches. Maybe try rebooting Router ?

Below are ping stats from one of my 3B+ to Router over 5G WiFi. Only one occurrence of a 10ms ping otherwise rest are < 1.5ms.

(10-08-2018, 01:23 PM)Tim Curtis Wrote: The regularly occurring 25-30ms ping times could be an indication of an issue if they roughly correlate to the audio glitches. Maybe try rebooting Router ?

Below are ping stats from one of my 3B+ to Router over 5G WiFi. Only one occurrence of a 10ms ping otherwise rest are < 1.5ms.

After rebooting, same problem is occurred on 4.3 ;(
But 4.2 is running without any problem...

What should I do next?

Thanks,

Audio glitches that occur only over WiFi <--> NAS connections can be difficult to troubleshoot because its actually a rare occurrence IME. If for example there were a general 3B+ WiFi issue in moOde 4.3 there would be a lot of trouble reports since a lot of users have 3B+ and NAS configs.

Some of the sources in past troubleshooting included the EMI interference defect in the 1st gen Hifiberry DAC+Pro, poor NAS throughput, poor Router throughput, WiFi signal attenuation from building materials, interference from other EM sources (microwave ovens, etc.). Even the Kali Reclocker would be suspect for EMI based on my tests.

If WiFi interference can be ruled out then examining various logs might show something. 

dmesg
cat /var/log/syslog
ifconfig (examine the tx/rx stats)
iwconfig (examine the signal quality/level)

You could also try rebooting your NAS.

Some other things to try might be to revert the Linux kernel to the version in moOde 4.2 and if problem goes away, then bump it forward to see which version the problem starts to appear in.

Also, remember to set WiFi county code.

Someone may have added a WiFi network on the same channel nearby, try doing a wireless survey with your router to see if there’s a new source of interference.

You could also try boosting the mpd buffer size, and how much to buffer before it starts playback, though it’d be more of a band-aid than a solution.

The thing about WiFi country code is true too, some countries allow higher power transmission levels or different channels than others.

Hi Tim, swizzle,

The WiFi country code is "Japan", of course, of course, and of course I tried to change MPD buffer size already, too.
But 4.3 does not work as I expected.

Next, finally, I tried to revert the kernel to 4.14.54-v7+ via ssh just now, however this modified moOde 4.3 didn't work well, the sound breaking up (choppy sound) is still occurring.

I don't think that the course is the Wifi connection issue at this moment, because there is no problem with moOde 4.2 at all.

Anyway I will switch back to 4.2 until this issue is fixed.
if you want any help this issue, pls let me know.

Thanks,

Very odd. IME 99% of the time, audio glitch over WiFi is caused by something external to moOde software for example WiFi interference, bad network adapter, misconfigured Router or Samba/NFS server, misconfigured moOde network settings, etc.

The WiFi adapter drivers are part of Linux kernel so if you reverted and no change it would suggest problem is somewhere other than driver or kernel. In any case, even the 2018-06-27 Stretch Lite will update to 4.14.70 when apt-update/upgrade is run. I'd suggest updating to latest 4.14.73.

Code:
echo "y" | sudo PRUNE_MODULES=1 rpi-update 9f230923e419d942cf02fe936ea4fd186d3a21fa

sudo rm -rf /lib/modules.bak
sudo rm -rf /boot.bak
sudo apt-get clean

You could try
- examining your Router syslog and wifi log for anything suspicious.
- specifying ver=2.0 or 3.0 in moOde NAS Config, Advanced, Mount flags
