Low Volume- Sonos Arc

Has there been a resolution to this?

I have the same setup as the OP. I solved this issues by going into the AppleTV4k settings, video & audio, then turned ‘Reduce Loud Noises’ to ‘Off’. I never turned this on, maybe it happened in an update. Hope this helps. 

Just got the Arc along with the gen 3 sub and surrounds. I also had the same problem and was tempted to return until I played with my setup and figures out what the issue was. Basically I had two issues. Not sure which of the two was the issuer if both were the issue. 1 I was connecting the audio via AirPlay 2 on my Apple 4K tv. 2 I also had the Arc connected to optical input via the HDMI/optical connector that came with the arc. I have an older TV so I did not think I had an Earc port. I believe when connecting to airplay it compresses the sound too much. Air ply works on my sonos 5 just fine but when connecting my system via airplay I also had to have the volume at around 70% to hear movies…never a problem with music. I decided  to unplug all the system from the power and removed the connection from the optical drive. To my surprise one of the HDMI port on my TV was an ARC not Earc, so I just plugged the HDMI to the arc port on my TV and it worked! Obviously i don’t get the full benefit of atmos Dolby until I upgrade to a new TV, but the system still sounds fantastic! I hope this helps those who have an issue.

I’m extremely disappointed in the arc I don’t know if it’s only me but the Arc is not wowing me at all even in the Atmos mode specially at this price point.  
and when I’m watching a moving I have to turn the volume all the way up for me to hear talking so I bought 2 times the one SL didn’t get any better 

is someone experiencing this problem or is it just me ? 
 

Same problems here - output from the television using HDMI eArc needs to be turned up to 80% or more to be a usable volume.  This happens with anything from the television - AppleTV, over the air content, DVD, etc. The Arc playing music along with other speakers needs to be turned way down to normal volume levels.  This seems to have started after a previous update and persists to this day.  Nothing helps - powering everything off, swapping HDMI cables, etc.

I had similar problem. I use ARC plus 2x ONEs both as a TV (hdmi) and computer (optical) (unfortunately i have to switch manually cables due to only one hdmi input).
TV via eARC and optical runs fine, but computer sound was very low. I tried different soundcards, transmitting sound via bluetooth, different cables but nothing worked…. until I inceased the volume directly on soundbar using touch controls <facepalm>.

A remote or volume control option in app would be useful.

Just to maybe assist you a little here…There is a volume control for the Arc in the Sonos App🤔?.. plus almost any infrared ‘remote’ can be setup and used to control the volume  of the Arc too, or it’s volume can be controlled using the connected TV remote over HDMI CEC and if you have an installed voice assistant (Alexa.Google) on the Arc, then something like ‘Alexa set the volume to 3’ (or any number between 1-10 inclusive)) will change its volume too. HTH.👍

Thanks so much for the suggestions but nothings seems to work and everything seems to point to the driver.  Manually manipulating the touch controls didn’t help as they directly drive the Sonos volume on the app.  I tried that with the HDMI cable connected and disconnected.  The volume on the TV itself is set to zero.  I’ve tried every sound setting on the set itself.  Nothing works.

I’m planning on a move in the Spring and will probably replace my Sonos gear solely based on this problem which is impossible to live with and not being addressed by Sonos.  I’ve been a Sonos customer for the life of the company.

Thanks. I’m familiar with voice control, but I just dont like it. And regarding the any infrated remote, this solution doesn’t work while my pc is connected. And yes, volumes on my pc are set to maximum volume.

An infrared ‘remote’ should work, whether your PC is connected, or nothing is connected, to the Sonos product - you just need to enable the IR sensor in the device room settings via the Sonos App.
