SPDIF compatibility issue

[mietse]

My ESP-Wrover-e board works with SPDIF on my Samsung soundbar.

Firmware 2.1539 and lower works fine, no problems.

Firmware 2.1597 and higher, SPDIF led goes on , soundbar switched on, but no sound.

When is flashed it back to 2.1539, the sound is comes back immediately.

What did i do wrong, or what goes wrong??

Thanks, Mietse

I noticed some issues with sample rates.

I have a 24bit 96k flac. Had to set the the reported rate to -Z 56000 to get it to play. The docs say its a 96k limit on the 32bit version, but I think the new 20bit system may reduce that.

@mietse adding logs helps kick start the analysis. @wizmo2 thanks for the input

[philippe44]

is this the 16 or 32 bits version?

[philippe44]

I tried both 16 and 32 on SqueezeAMP and they both work, so we are probably missing something here

[sle118]

logs would be a good start. Thus the incomplete status for this issue

[sle118]

@mietse could you try the latest release?

[mietse]

is this the 16 or 32 bits version?

Test Only the 16 bits versions.

[mietse]

Sorry forgot the logs. working setup: LOG=v1.0-1539-16.txt

Not working setup: LOG=v1.0-1619-16.txt

[mietse]

@mietse could you try the latest release?

Tested, and no luck... no sound. )-:

[philippe44]

So I guess the change is this PR https://github.com/sle118/squeezelite-esp32/pull/307 which works 100% for me on tested cases and for the author as well but it might be an issue with your soundbar not being happy with the change to the format. @UrbanLienert, can you chime-in?

[sle118]

Ah this might be a good explanation. Because it does work for me as well.

Thanks for the info, i think that the changes in the spdif code not oke is for the soundbar.. It's the samsung soundbar q930b.

I think I just ran into this with my old Onkyo receiver. Had it hooked up by SPDIF and after update, no sound. Works fine on my Yamaha pc speakers…

There seems to be a bug somewhere in the code. The new SPDIF version should be as compatible as the old version. Did you check the 16 and 32 bit version? Do you connect SPDIF via optical or coaxial cable?

[philippe44]

Oh I think I see the problem - I need to learn how to count properly 😃. I'll fix that tomorrow

Optical. Only 16 bit checked. I have squeezeamps

[philippe44]

Can you try the artifacts of the version that is being build as I write that (I won't publish before I'm sure). https://github.com/sle118/squeezelite-esp32/actions/runs/6632316221

[emlynmac]

1625 did not work for me; 16 bit version.

[philippe44]

oh well, I might work better if I fix the 16 bits version as well. Let's see 1626

[emlynmac]

Thanks @philippe44, confirmed working again

[philippe44]

BTW, it was my fault, not @UrbanLienert PR
