Since you are using latest beta ROM and assuming you haven't flashed any non ARB ROM to keep anti 3
You can flash any ROM with ARB or without ARB no need to sorry but do not flash older firmware
If you have low headphone sound then change region to India or Switzerland

No sir I am using custom rom..

1. Headphones or speaker?
2. Is the volume control always on high? Does it change when the sound goes down? And Is it ever loud enough or is it always low?
3. Why do u think firmware is the problem?
4. What official miui rom where you on before you flashed it?, so we can identify the software more

Q about rollback

—Answered— Thank You!!
Hi, I just bought Redmi Note 5 today and after I turn it on, it is already on MIUI 10 8.7.5 Global Beta. The question is, can I roll it back to to MIUI 9.6 Global Stable? Because I found this rom isn't comfortable and I found so many bugs. I don't want to update it to MIUI 10 stable yet because ppl in MIUI forums complained that there are some bugs.
Thanks
Wtf...New device came with Developer beta rom?

8.7.5 miui 10 is ARB3 you can rollback to 9.5 miui 9.5.17.0 thats last ARB3..
or get 9.6.4.0 thats ARB4.
How come new device comes with beta ROM?? Something wrong with reseller please contact ask them
Right now your device is on arb3 (no antirollback) you can upgrade to latest version with firmware less ROM

You can directly go from MIUI10 to 9.5.19
After downgrading just do a factory reset

I am on Pixel Experience rom, and want to try another rom, Help me

I am on Pixel Experience rom, and want to try another rom. I was on MIUI 10.02 and I unlocked bootloader and installed PE rom. Now I want to try another rom, but am afraid of bricking phone. Is it safe to flash another custom rom? or what?

Flashing Custom ROMs is safe leaving aside MIUI based custom ROMs.
Go from Oreo to Pie or Pie to Oreo without a doubt in any AOSP or Lineage OS based ROM, but if you ever want to go back to MIUI or any MIUI based ROM just ensure that you install the latest version or the version higher than the one you had previously.
Only the firmware found in MIUI ROM is responsible for bricking. So you can also try firmware-less MIUI ROMs. There are many relevant threads regarding it.
Just do a search.

Ok what are roms that based on miui to avoid them?
It's easy to find by the nomenclature.
Their names include MIUI or a variation of it.
Some are: Revolution OS, MIUI Pro, MIUI Eu, Masik ROM.

Did u mean that miui based rom can brick my phone ?
Did u sure for that ?
I think the only way to brick it to go from arb4 to arb3 in miui official rom only but the miui based roms i dont think so .... But if u sure about that tell me again ?

I mentioned that you should always install a MIUI build that is of higher version than you previously had to be on the safer side.
After MIUI 9.5.17, ARB protection bumped to ARB4 from ARB3.
So, once you update to any ARB4 version and then make a mistake of installing any MIUI build of ARB3, your device will be bricked.
That's why I mentioned that always ensure that you install the latest build or the build with version higher than the one you had previously installed.

I believe his question was about custom MIUI roms which have firmware update removed so that risk of bricking is non existent. I believe reading that Masik does not contain firmware, but I'm not sure.
Other than your good explanation about ARB4 vs ARB3, one thing to add: anyone on ARB4 can flash any ARB4 rom since the bootloader checks for anti rollback protection index but not the MIUI version specifically. So any rom starting from Stable v9.5.19 if I remember and Beta 8.7.6 are safe, until ARB5 comes (if it comes, and if it requires ARB5).

as long as they tell you in the rom features or installation that doesnt affect ARB or doesnt touch firmware its ok.. but not sure if not all miui based roms have firmeareless. so you need to read rom intructions.

PE Extended. Also depends on the Kernel. But nothing like MIUI gives you better battery life.
try mcaosp rom... you won't switch to any other rom ever... best custom pie rom in my opinion. or if wanna go for miui based go for masik x1.7

What is the difference between those firmwares?

Hello.
I want to flash latest firmware, running Syberia ROM, but I want to know what are the differences between: FW, FW-less and FW-non-arb?
Thanks.
If you are still anti rollback (arb) 3, installing the latest firmware (FW) will update your bootloader, thus you will have arb 4.
Fw less roms come without the firmware. since there is no firmware, no way to trigger ARB.
Fw-non-arb are firmware files without the bootloader part, again no bootloader so arb will not be triggered.

Since 8.12.27 is the newest rom available you can install only FW as this would not trigger ARB (Both 9.6.4.0 and 8.12.27 are ARB4)

About Firmware (custom ROM)

Hello. Tell me, how can I find out what my FW is installed? Oreo or Pie version... maybe there is even some kind of application for this?
It's in the About phone section in Settings dude

No, it's not lol, android version is different from fw version.

Yeah I have same question. Right now I'm on Pie FW just because of Pixel Experience ROM. I want to try Havoc OS but it's using Oreo FW. Is it possible to flash Oreo FW safely? And which variant? Just asking because I have ARB no. 4 and I'm little bit scared of brick. So anyone? Thanks

Yes, you can flash Oreo fw without brick. Just be sure to flash the latest Oreo fw.

Question about arb

Hi, right now I'm in the last pie firmware stable, if I want to downgrade to Oreo last stable. Is the arb will triggered? And my phone bricked?
Thankyou

If the ARB of your current ROM and the ARB of the ROM you are going to flash is same then there will be no issue in downgrade.
The risk involved only when your downgrade to a ROM whose ARB is less than your current ROM.
You can't only flash ROMs older than 9.5.19 global stable and 8.7.6 global beta, so no worries about arb thing.
