The recording was discarded because the audio was completely silent. This device might not support recording calls associated with the 'com.android.phone' app. about bcr

[chenxiaolong]

I'd suggest changing the output format to WAV/PCM and the sample rate to 48000 Hz. If that also doesn't work, then it's a ROM issue. With those settings, the recorded audio is byte-for-byte exactly what Android sent to BCR.

(BCR is already compatible with QPR2. QPR2 had a huge number of changes and is closer to Android 15 Beta than 14, but those changes don't impact BCR.)

With Official LineageOS 21 on my kebab (oneplus 8T), switching to WAV/48kHz doesn't solve this problem.

I'm having this issue on a Pixel 3 running LineageOS 21 (Android 14). I was able to get recordings working using the WAV/PCM at 48kHz workaround

EDIT: Now the default works too! No clue why

[Naushikha]

Yeah this was weird,

• first try (after installation); it failed
• searched through the issues and came up on this thread
• then I switched to WAV/PCM since it's a recommended solution
• awesome, recording works now! but the file size is too damn big
• out of curiosity, switched back to default OGG
• still works!

How though? o.O

btw my specs:

• Pixel 5 with LineageOS 21 + Magisk 27
• Flashed NikGapps Pixel Basic Package (which includes the Google Dialer: com.google.android.dialer v129.0.628891516)
• Flashed NikGapps Pixel Specifics Addon (Pixel Launcher + Other goodies)

[Hellsingoff]

Same here. Redmi Note 10 Pro.
crDroid 9 (android 13), bcr 1.37 - worked fine.
Update to crDroid 10 (Android 14), bcr 1.66 - didnt work, "completely silent record" error
Rollback to crDroid 9 (Android 13), bcr 1.66 - same error
With wav/48khz settings - works.

Tomorrow i'll try update to crDroid 10 again and set same settings there

With official LineageOS 21, Android 14, without google on my Kebab (oneplus 8T) switching to WAV/48kHz does not solve this problem.
Version 1.57 saves the call recording, but there is only silence for 1-5 seconds.
Versions 1.60; 1.63; 1.65; 1.66; 1.67 do not save the call recording!

1.59 works fine
1.63 desn't works
so maybe the issue was introduced in 1.60

[PKutok]

After the August 2 update LineageOS 21, Android 14, OnePlus 8T and BCR update to version 1.69 - the call recording began to be saved. This happened after the second attempt.

[chenxiaolong]

Are you on a Google Pixel device? If not, there's probably not much you can do to make it work. On non-Pixel devices, call recording usually only works on ROMs that are based on the device's stock ROM.

no.. I'm using a Xiaomi phone with project elixir custom rom installed in. Apparently BCR worked fine for me in multiple roms including elixir but as soon as I updated the aosp qpr2 update , this message shows up. The rom devs told me this issue is common for qpr2 update roms and the only way to fix this issue is to wait for the BCR release that supports qpr2. That's why I thought of mentioning this hoping there would be an update for BCR.

[TomerGadol]

I also have this issues after updating ROM. On previous EvolutionX (which had BCR installed by default) recording was working fine. Now on latest Derpfest (qpr2) I get the same error. Tried the above settings of WAV/PCM at 48000Hz but still silent. My device is Xiaomi Mi 9T.

Commenting to this issue because I had the same problem of OP on my Xperia 10 IV device with Android 14. Changing the output format to WAV/PCM at 48kHz worked.

[ask9027]

i am using AwakenOS , after installing BCR with KernelSU,
call recording is silent.
hiw to fix this?

I am a Pixel 6 Pro user and have this issue for the 1st time after updating to latest release.

[RunasSudo]

Had the same issue and very surprised to find I could reproduce the fix. After changing from WAV/PCM to OGG and recordings working correctly, changing to FLAC also works.

Specs:

• Pixel 8
• Stock Android 14, build AP1A.240405.002.B1
• Magisk 27.0 (27000)
• BCR 1.63 flashed as Magisk module

[ask9027]

install apk as normal install, then flash zip in magisk or KernelSU,
it will work.

I just installed qpr3 on my stock pixel and I'm getting the same error despite bcr working just fine before

[tommy1735]

just want to say thanks to chenxiaolong, change to WAV worked for me, phone is a xiaomi redmi note 9s with lineage OS 14 useing magisk

[Asunix666]

For me, neither above fixes worked. I'm on NUBIA REDMAGIC 9 Pro android 14 stock firmware. Since 2024.07.19 update, the app is broken. Please find a solution. I use this for years. Others don't have noise cancelation.

[PKutok]

Version 1.59 works poorly - saves, but does not play.
The problems began after the LineageOS update, July 19 and July 27.
Before that, BCR version 1.65 worked fine.

[Asunix666]

Still nothing for me with NUBIA REDMAGIC 9 Pro android 14 stock firmware. 2024.07.19 update.

[mikelpr]

This happens to me on a Pixel 8 Pro on 14 AP2A.240605.024

EDIT: apparently in my case was happening because I was dialing a number which I have in my contacts, but then I don't know why I was getting the notification that it was recording and then the failure notification

[ztmzzz]

On my Pixel 8 Pro AP2A.240805 version, changing to WAV/48kHz works for me. After successfully recording a call, changing to FLAC also works.

[desson-ctrl]

Hey folks, I got it to work on my phone after trying several versions and several output formats. The fix for me was to turn off the "Record calls before connection" switch.

Now working with crDroid 9.18 android version 13 bcr ver 1.69 any of the output formats.
