Hello,
it's me from Germany again...
My BDP-2 still has the original sound card (prior IAD kit) and an internal SAMSUNG SSD 1TB with all my music files on it (all .mp3 320kbps 44-48kHz, 180GB with 25.000 files used). I unfortunately have a problem playing these songs using MM through MPD 0.19.21 (changing to 0.18.21 does not help) and coax output. The music being played interrupts (gaps from 2 to 10s once in each song). Time counter from Music Player also stops during the gaps. Playlist length and source don't matter (tried different length 2 to 1000 songs either from internal SSD or thumb drive at ext. USB). Checked the library, but no corrupted file found. Meta data all o.k and will be displayed in Music Player. All reboots, DB updates etc. didn't change a thing.
Now i recognized the following strange phenomenon:
I did a backup over LAN of the 'media' folder at the BDP SSD to my PC (Windows). It took 1,5hours. During that time i played music with the BDP. AND during the transfer time (1,5h BDP SSD busy), not a single interruption in the songs!!! After the end of the transfer, the gaps in the songs appeared again. Confirmed that twice by backing up the folder again and again: transfer -> no gaps, transfer finished -> gaps again...
I have no clue, what's causing this behavior and what the solution could be (i cannot copy files all the time when i use the BDP)? Any idea would be very appreciated. Please help (contacted official BRYSTON support already, but no reply yet).
For the moment i can not listen to my DAC with USB connected (no analog connection to my equipment), to tell whether there are interruptions too (indication stays locked at 44/48kHz during the gaps). Working on it...

Just some additional information:
According to my ANTHEM processor, who receives the digital signal from the BDP, the PCM stream is not interrupted. Just the music on it. When listening to BDP's bRadio there is no interruption at all.
I did benchmark the BDP SSD through the dashboard disk information:
- Bench without active transfer of files to the PC: 27.0MB/s
- Bench with active transfer of files to the PC: 58.8MB/s

I have a BDA3.14 with about 5TB on SSD's in a NAS and I had a similar problem. I am far from technically savvy but put it down to the limited processing power in the BDA. I have switched off the automatic update and whenever I add music I clear the cache and reset the db and wait for it to go through the reset before using. Since I have done that the gaps are gone. Hope that helps.

Thanx for the valuable information. I'll check that and report...

My personal belief is that it is corrupted files on the hard drive. That's why I'd never through away my CD source for music files. Sometimes files need to be re-imported.

[abk456]

In my case, I ruled that out because the interruptions were not always in the same place on the same track. My assumption was that with a large library, if the machine was performing another operation while also playing back music one or other of those tasks might be compromised.

Have. you ever had an issue wherein the unit skips tot he next tract in the middle of the existing tract?

[abk456]

Once or twice when my nephew plays with the remote but otherwise not that I can remember !

[soopergoo]

Perhaps try copying some of that same music to a USB Drive or USB Flash Drive and see if you have the same issue.  It might help narrow the problem down.

[klotz777]

Hello soopergoo,
thanx for the valuable tip. I did copy some music files from the internal SSD to an USB stick and played them through one of the external USB ports. But unfortunately no difference, still interruptions in the songs. Sounds to me like a pre-buffering problem. But how to change the buffer size?

Cheers

[soopergoo]

Hhhhmmm.  Not sure about the buffering answer.  I am having different issues with my BDP3 freezing up and Adam suggested two things.  One is resetting the DB.  Under Media Player, click/tap the gear symbol and scroll to find and select Reset DB.  The other is more invasive and will wipe your playlists and that is to set the device back to factory settings.  It is under System and Reset to Factory.  Then rebuild your library. 

I have spent a lot of time struggling with the BDP3 in the least 6 months and it is a wonderful piece of hardware.  The software absolutely is in need of an overhaul.  Rumor has it that it is in development.  I hope they give the user community a chance to chime it during the beta phase.

In the meantime I am using the squeezelite service with my LMS server and it is rock solid.

[klotz777]

Ok, i did the factory reset, no help. I checked playing music (MP3) from internal SSD and external USB-stick through USB to my DAC, still the same behavior: there are interruptions/gaps in the songs (1-10s). The time indication of the MPD also stops during the gaps but the DAC stays locked at 44/48kHz during the gaps, only interruptions in the music. The music files of my library/DB are all checked with 'MP3val', all error-free. Still thinking, it's a buffer problem... Any ideas?
I will try .flac/lossless files next through USB and my DAC... Will report.
Cheers

Hi, I have no experience with this issue but I would suspect two possible causes:
1. CPU workload over 100% when changing from one track to another - less probable
2. SSD have some aggressive standby settings; bryston reads in memory the file, ssd is not used and enters standby; when new track is requested, bdp tries to wake up ssd and something is causing a lag

For hypothesis 1, if you login via SSH to bryston, issue the comand "top" and will se the processes running and if something starts between tracks and consumes resources; I know there are some processes that are looking for albumart, in order to change the cover displayed during the playback, but are not that heavy on the resources.

for hypothesis 2, I recommend to use an AI companion to guide you via some settings changes via the SSH terminal
When explaining your situation to Google "AI mode" I got some indications that seems plausible:

Since you cannot change how the operating system handles power management, you must instead change how the SSD hardware handles it. You can do this by executing a direct hdparm command over SSH to disable the standby timer.
If you are comfortable logging into the Bryston BDP-1 via SSH (using an application like PuTTY on Windows or Terminal on Mac):
- Log in via SSH using your BDP-1's IP address.
- Find your drive's name by typing: lsblk
Your internal SSD will likely be labeled /dev/sda or /dev/sdb

- Disable the drive's sleep/standby timer completely by typing: sudo hdparm -S 0 /dev/sd? (Replace ? with your actual drive letter)
The -S 0 flag tells the SSD firmware never to enter standby mode.

- Disable Advanced Power Management (APM) by typing: sudo hdparm -B 255 /dev/sd?
The 255 value completely disables hardware power management on the drive.

The Catch: Because the Bryston OS resets itself on reboot, these commands will stop working the next time you power the BDP-1 down. If this fixes your playback gaps, the ultimate solution is to remove the SSD, connect it to a PC, and use the manufacturer's software (like Samsung Magician) to save these power-saving disabled settings permanently into the drive's internal firmware.

Hi ttsto,
thanx! You're the man! Entering the 'sleep-mode' would explain, why there are no interruptions when i transfered a larger amount of files (26000/1.2hours) from the internal SSD of the BDP-2 to my PC during playing music from the BDP. The SSD is busy and will not enter sleep-state.
Unfortunately the 'sudo' command will not give me the necessary rights/privileges to execute the 'hdparm' command as 'root on bryston-bdp-2' . So, i choose option 'B' and will remove the SSD from the BDP and disable power-saving settings all together with my PC. Could take a little until i will do that. But i keep You updated.
Again, thanx so much for the tip.
Cheers

[ttsto]

You're welcome!
root is also with pwd bryston, but is anyway a temporary solution

funny thing, before owning BDP player I never used PuTTY or knew what SSH, SAMBA, hdparm would mean
and Linux was something I learned about too many years ago in university...
