Thank you very much. My Play 1 had a small dent in the grill, but now I have fixed it. Thanks for the video.
very very cool video, looking forward to see this project
Thanks for the video. I also had a small den in the grill. This video is much appreciated! - Mike (Blackpool - England).
Mike Hill I've just knocked mine over and dented it.. How does that rubber stick back on after you've removed it?
just dented mine...that's why I'm here 2 years later.
Thanks for the video. Following was really easy and so too was taking apart.
People who are curious (like I was) about using it as a cheap sonos connect amp - unfortunately it doesn't work very well. The speakers in the play 1 have cables between the amp and each speaker (unlike speakers you buy in the shop). This means you either get all low + bass or high for tweeters.
The pairing of amp with speakers is very specific. Using another speaker with correct wiring was still too basey
Would love to know how you got USB power working!
Hi
Just wondering how you got on with the next stages of these Mods? I'm also interested in altering a play 1 to make a cheaper rca output sonos.
Any update to this video ?? really interested to see your progress. Did you find out if the DAC is using both channels ??
Hi brilliant part 1 video but can not find parts 2 & 3 video's can some one point me at where to find these.
Regards
Paul
Would it be possible to hook up new extern speaker to the play:1? that would be great to expand my old jukebox, which got no line in, but has more speakers inside.....
One year later....any movement on this? Perhaps using a raspberry pi to convert audio to digital and broadcast onto the sonos frquency?
Thanks. I was thinking that and have an input.
DO you know where I can get mid sub woofer replacement for play sonos 1? compatible generic
Thank you for sharing this video. I can't wait to see the next part. I have been wondering about the possibility of wiring a powered sub to the speaker level out using a line level converter. What do you think?
Did you ever get info about doing this?
Thank you very much!!!
Thanks! Something was splashed on mine and I just can't rub it off as some dirt is stuck the tiny holes of the grill and I want to take it off to wash it. It looks so aesthetic, but not when it looks like someone spit on the grill. :)
Does anyone know, how much Watt and Ohm the woofer needs?
Komt er nog een part 2?
Kun je met de mod ook je sonos gebruiken zonder wifi?
Hi, bad news. I just want to let you know that i'm giving up on trying to get audio line out out of the Play 1. With help of a scope and a logic analyzer i did some research on the Play 1 internals and here are the reasons why i'm not investing further on the planned hardware mod. 1) Unfortunately the I2S output of the Play 1 really is mono. The audio will only
output to one channel of the PCM5101A DAC which makes sense here since the TPA3112 AMP is being used in MONO mode (see Datasheet). So the DSP inside the Play 1 is mapping the stereo signal to just one output channel. I tried to get the DSP to output the signal as stereo but had no luck. The only thing i got working was switching between L+R and R+L.
I even created special audio files with sinus tones to test that. 2) The audio signal is heavily optimized for the speaker enclosure so even if you get the signal out it won't be a clear raw audio signal. 3) The DAC chip is quite small so it can be easily damaged if you try to alter any solder points. I really was afraid to turn my Play 1 into a brick but luckily it is still working. So my suggestion is to just get a Sonos Connect if you wan't to get line out. However since i can't afford a Sonos Connect right now i'm planning to do some experiments on the software side. My plan is to grab the audio stream and play it with a rapsberry. Thus i could get clean audio out. With this there is however an issue regarding audio sync.
Thank you so much for placing your research. This will help a lot of people! Great work!
Huy Do Fantastic work so far. Do you have a forum or mailing list that you're using for your effort? Would love to participate.
Thanks for the update, this is super valuable and saves me and others tons of time. You rock!
maxslug1 Unfortunately no. There aren't any forums where i'm participating in regarding sonos.
Huy Do Keep up the good work. You're not the only one who wants what you're looking for, but you might be the only one actually looking for it.
Can anyone tell me what size the thermistor TH1 is? And perhaps whether it is a ptc or ntc?
part 2 please
Please please please post the next installment :)
Since Gil hasn't responded i assume he didn't try the modifications yet. I just ordered another Sonos Play 1 and
a DAC module (Sabre ES9023). Once i get the parts i'll definitly try this rca line-out mod. I'm also curious
whether the Play 1 is capable of stereo-out. I'll post a video when i successfully did the mod.
Best of luck, and please do post back, I had thought doing a PAC SNI-35 line level car audio converter off the speaker output, but was worried that sonos might be outputting different frequency ranges to the tweeter and driver and haven't been able to find anyone who has done it yet. Best solution would definitely be to tap in from the digital signal if possible.
Daniel, I doubt you'll have good quality audio with that method due to what you suspect regarding the EQ of the output. What we need is someone with experience with converting I2S output to SPDIF output. Most I2S/SPDIF boards that are currently available have a lot more functionality than we probably need and cost around $60 USD. Plus, they require a little work and know-how to (maybe) get working. Hopefully someone with a strong electronics background can help us all out. I have yet to purchase any Sonos equipment.
Gil Harari isn't the I2S data already equalized by the Sonos controller? I don't think this will be raw audio data.
HackThatNow There may be some eq done by the processor, yes. I would think this would be user settable through the sonos interface though. I would think that the sound shaping to suit the speaker would be done q
By the amp circuit on the analog side though. I'd think that the DAC i2s input would be very good to use as a raw signal. I'm speculating though.
After the sonos is opened could I connect the speaker output to a powered subwoofer to make a sonos subwoofer? Thanks for any help you may give.
I think it should work, but you will have to convert the speaker output to the line input of the sub.
I just finished adding outputs to a Sonos Play 1, my question to you is, do you know how many Watts the internal amp can handle?
Sorry, did not measure that, maybe someone else?
YourWizBlog Thanks for the reply. I ended up grabbing the spec sheet. My unit had the TPA3116, which said it can drive up to 50w and up to 100w in Mono mode.
the R178 resistor on my board went dead. Anyone can look it up on their sonos 1. r178 is located on the other side, just underneath the most blown resistors R525 , R423 and R524
So has anybody figured out how to wire an Aux input for the Play:1?
I can only imagine with raspberry pi as in aux-in -> ethernet -> play:1
Having a hard time finding the rest of the videos especially where to connect the the DC input
Could you do this with the Play 5? :-)
I would love to if you can supply me a PLAY:5 since I do not own one ;-)
Sorry, don't know if I could risk my beloved Play 5 haha, but understandable.
By the way, The best setup is is two Play 5 and a Sonos sub! I love it :)
Daniel San Is that cost effective though?
Nope - not at all!
Is it possible to make line out.? I hate Bluetooth.
Yes it is. I've actually done it on my speaker. If you think about it, the speaker must be driven by an analog audio signal, therefore, there must be an amplifier driving the speaker(and there is). If you can disconnect whatever is driving the amplifier and connect your own signal you'd be in business. I did this and it didn't work, so I dug deeper and found a digital signal connected to the "mute" line of the amplifier was disabling the output of the amplifier so I shorted the mute line such that the amplifier is always driving whatever input signal is there. After that it was bhangra all day!
Hi Can you do a video or how-to-guide how to this? I have simply connected a headphone plug to the speaker connectors (combining the high and low speakers) but when playing this works up to a volume level of "5%" or so and then the audio is dead untill i lower the volume again. I guess this has to do with your problem?
Jeroen Arends hi did you ever resolve your low volume headphone jack set up? I can't think for the life of me why it would do this? Let me know thanks 👍
Sonos is trash but this video is the opposite
