    Hello Rashad, 

    The update released yesterday was not for the app, rather it was for the BluOS firmware itself. This update did not include any changes to the audio decoding.

    In any case, I have run some tests regarding this my Node here and do not find any discrepancy between the SUBW OUT output between the two versions. 

    I would recommend disconnecting the sub cable from both ends (Node and other end), rebooting the Node and sub, and then reconnecting the cable to see if that resolves the issue.

    Regards,
    Sam R.

    Edit: for all generation Powernodes, the Subwoofer output was dropped to meet DOLBY mix requirements in 3.10.

    To adjust for this change, please increase the gain of your subwoofer by 15db.

    For all other model Bluesound players, please see my above comments. 

    Edit 4: Paraphrasing Tony W.:

    Within the next 24 hours, your BluOS Player should prompt for an upgrade to install (BluOS v3.10.3) via the BluOS Controller app. We are pleased to announce we have restored the SUBWOOFER output on the POWERNODE to the original output setting.

    If you do not automatically receive a notification to upgrade, please manually check for this via Help > Upgrade (Player).

    Thank you for your continued patience and understanding.

    As a heads-up, please turn down your gain on your SUB before installing this update.

    I forgot to mention that I tested both Tidal and Qobuz within the BluOS app and bass output is weak with both so it’s definitely an issue with the BluOS app itself

    I am also getting really weak bass but I just bought my Powernode 2i. It is paired with Q Acoustics B12 and 3050i speakers.

    hi, I'm also having this issue after the update

    I am as well. I noticed something wrong directly after the update. My JL D110 turns on automatically when it senses a signal and when I played the same playlist I always play it didn't turn on on the first song. It finally turned on after playing a song with heavy bass and the normally heavy bass was extremely low and the woofer cone was barely moving.

    Bluesound - yes - there is something wrong with this recent update that is affecting sub signal output. Please investigate this.

    I had to click the reboot button within the app and it resolved the issue. Hopefully it works for you. The bass was definitely  an issue though initially

    I'm not looking at it right this moment but I remember it was under settings. You can find settings on left side once you click the 3 bars at the top left

    Hi Rashad - found it under Help / Diagnostics / Reboot. 

    Rebooted.....issue still there. Sigh.

    Try removing and reinstalling sub cable also. Don't know if it will fix the issue but worth a shot. Hopefully Bluesound is working on this issue. I know it's very frustrating for you as I was the same way at first

    Yup did that before the reboot. Also unplugged the Node 2i as well. In theory, everything should have reset yet I'm still having the issue. Very frustrating!

    Hi, I'm also having same issue. Seams like my sub doesn't sense a signal on low volume. I had no issue with this before the update. Please look into it. Would be great if you could control subw out signal level.

    thanks,
    Thomas

    Even before this update, the sub will not wake up from standby mode, which mean the powernode 2i has very low level signal problem here, my other amp/receiver don't have this problem, I have found this specific issue only in powernode 2i. Reset to factory and reboot does not fix this issue at all, even using the equalizer does not fix this problem.

    I sent back one Powernode 2i to amazon because I thought the sub out was defective with this issue. Now I am sending back my subwoofer as BluSound is claiming there is no way it is there problem. If I get a new subwoofer SVS SB-3000 or other suggested and it is not driving I am going to be frustrated. I might just return everything for good this time. 

    I want HiFi audio but I cannot dedicate this kind of time to it. For this much money things should work fairly easy. Also noticed music is loading extremely slow on the last update and the Powernode 2i is turning on music by itself sometimes. So Frustrating. on paper this thing looks great.

    rgarner83 - this is absolutely ridiculous. My local audio shop has a call into their Bluesound rep to investigate. After your comment - I'm a bit nervous. I mean all Bluesound has to do is actually test a Powernode 2i with a sub and they will immediately understand. This is ludicrous - my focal 706s produce more base than my expensive JL sub does right now.

    absolutely same problem here. Come on Bluesound!

    Same thing. I was listening to one of my favorite song, update, my favorite song again but no more bass. Fortunately, +6 db in bass, volume at 50% and a little bit of bass, my sub still works... For fun, tip above by unplugging sub, rebooting, etc. but no change. I'm an ITer, I can understand that it wasn't your goal, but there is a side effect: the volume of the sub is lower. Dear Bluesound, give us a fix or allow us to rollback because, at the moment, the PowerNode is of no interest for those who have a subwoofer.

    Sam R. - What say you? I think we deserve an answer that does not include rebooting our system, unplugging/replugging in anything, adjusting our bass level, toggling "with subwoofer" or "without subwoofer" or adjusting anything on our side. In other words I don't think the costumers own this problem and it needs to be escalated to BluOS/BlueSound support.

    Also would it be so hard to allow better controls over our subwoofer like crossover and output levels. People have different size speakers and needs (Hip Hop, Jazz, Rock, Country, Folk, Classical and Cinema).

    Sam R: Edit: for all generation Powernodes, the Subwoofer output was dropped to meet DOLBY mix requirements in 3.10.

    It seems that dropping the bass output by 15db to meet Dolby mix standards for surround sound from a stereo Hi Res streamer like the Powernode defeats the purpose of Hi Res.

    My subwoofer gain is MAXED and I can barely feel any bass at all, this is a joke

    Hello Bluesound support crew,

    the subwoofer output level is a real problem, my Bluesound DUO 2.1 sub is now almost useless...

    A very similar s/w version error also happened 3 years ago. Introduced in version 2.14.0 (-9 dB drop) and resolved in version 2.14.5 (December 2017).

    Tony W. was my main Bluesound support contact at the time on my support crew request #53851. Or refer to this community post https://support1.bluesound.com/hc/en-us/community/posts/115008292207-Sub-level-went-missing-after-last-update.

    Please correct the Bluesound firmware!

    Thanks

    Sam R. - Let me know if it is going to stay this way so I can return my Powernode 2i within the 30 day window. I bought this for HiFi Music not surround sound and if that is going to be the priority then I need something else. I have my gain up all the way and can barely hear anything.

    It just seems like if they can have a toggle for "Subwoofer" "No Subwoofer" then they can have a "Surround 5.1" "Stereo 2.1" toggle. Then we can all be happy, of coarse even better would be complete control over crossover and gain.

    So bluesound trying to get people to convert powernodes to surround sound! I didn't buy mine for 5.1. I already have surround amp. I want hi Res stereo which is why I bought powernode 2i. Will this change? If not I will have to return it because it's no longer for purpose

    Sam R. If this problem is not solved please let me know how you will organize the refund of the Bluesound sub i bought 2 months ago. It worked already at the max. setpoint and additional increase is not possible as you suggest so this sub becomes useless. Look forward to read your reply. I have send you my complaint yesterday under your ref. (#193390).

    As far as I know (Definitely not an expert) most subwoofers do not have a 15db gain. Most do 10-12 that I have owned, some only 6. Not to mention most of us need that gain reserved for more headroom, some older music has weak bass. We should not have to max out our settings for subpar bass, this is not acceptable.

    For those of us awaiting an official response, and hopefully a solution, regarding the weak sub out signal after the latest firmware update, I found that by using a Y adapter to the sub inputs L + R appears to increase the sub volume somewhat.

    As mentioned, the official response is to tweak your hard controls on your sub to increase about 15db. This was done to meet DOLBY Certification requirements. There are also soft settings in your Audio Settings (in the Player Drawer or under Settings, Player, Audio) to Boost your sub and increase the volume. 

    That being said everyone's above feedback has been passed along to our Product Management Team for consideration regarding the POWERNODE primary use as a 2 channel amp versus it having the option to be used as an AVR substitute and how we can better manage that as quickly as possible.

    Thanks for your patience.

    Hi Tony W.

    The problem is that the weak sub-out signal does not even trigger the sub to power up.  Increasing gain on an off sub does not help.  Even after forcing the sub to power up by playing a strong bass track, the sub would go back to sleep after a while.

    Perhaps you can add an option just for set-ups that require following the Dolby standard.

    Thanks.

    I will be returning my Powernode 2i by 09/04/20 if there is no resolution to this problem. I just can't wait for a fix that might not ever come. I might return the product anyways, it is incredibly insensitive to your customers to release such an update without a beta test and without community feedback. I have a lot to think about :(

    No offense but the market is saturated with AV Receivers, I thought the Powernode 2i was something different for us that wanted HiFi.
