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

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.

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.)

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.

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

[Cheetoacidosis]

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)

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
