Chromecast Audio dropouts


I and some others have had good success with Edimax dongles on the RPi - the stock WiFi is dreadful. I use the Edimax EW-7811Un and it has generally been very stable.

Hi Dylan,

Would you please give us an update?

I am using a cca with a Denon avr x6200 receiver with built in DAC. I’ve tried different optical cables and tried both the cca both wired and with wifi.

Occasional dropouts remain when playing hires MQA files from Tidal.

My Roon core instance is on a very fast nuci7idnhe ubuntu box.

If I use this box as an endpoint and play tidal MQA over hdmi I’ve no issues.

I’ve got 8 cca devices in different rooms and the dropouts are very annoying. Would you please give an update on this issue and help fixing it?

Thanks in advance!

Thank you @dhusky, I will investigate and give it a thought.

Just tagging in to see if anyone has come up with a fix. Been chasing it from all angles with no success.

As far as we know, the 96kHz dropout issue with CCAs is a firmware issue that was introduced in a firmware update sometime in July. Google seems to know about it, but as far as we can tell by what they’ve said publicly, they haven’t prioritized a fix. It’s a problem affecting anybody trying to do 96kHz output (not just Roon) and unfortunately, I think the most productive thing you could do right now is speak up in Google’s product forums to let them know that this issue affects you (as well as to provide more debugging information for them).

I’m having the same when running toslink optical from CCA into my CXA60. Any news?? Firmware 1.36…
Love the CCA, but the dropouts kill me…

(Derek Wyman) #68

am I better off (as a workaround) to (a) disable MQA when playing through the CCA or (b) using DSP to down sample everything to 44/48?

I only have a few 96 or 192kHz flacs to worry about if I go with (a).

I came across this thread and it got me thinking about the CCA I use to listen while working on my computer. Per Roon recommendations / Audiophile it’s in worst case territory:

Windows 10 NUC Core music on internal 2 TB SATA HD -> Orbi Router 1 Gb -> Orbi Satellite W-Fi -> CCA Wi-Fi -> Denon 3808CI Analog -> ELAC Debut 2.0 B6.2 MediaBridge 12 ft 12 AWG Cables

I don’t own much Hi-Res music but I do have 5 24/192 albums that I downloaded from HDtracks so I put them in a playlist and listened to them for a couple of hours. Per the Signal Path:

Everything is sent to the CCA as 24/96 and to my untrained 65 year old ears it sounds fine and I’m not hearing any dropouts or other issues I can attribute to a CCA problem.

Are CCA dropouts still a problem?

FYI my CCA is running Cast firmware 1.36.141215.


(Derek Wyman) #70

I just tried it and still get the dropouts on anything over 48.

(Andrew J Shepherd) #71

Chromecast Audio dropouts seem to affect TOSLINK optical output, not analog output. If you are using the latter, you might not be affected.


(Tim) #72


I thought I had read earlier in this thread that it affected both outputs but I’m probably mistaken … us old guys have frequent issues with CRS :sunglasses:

I have a TOSLINK cable so I’ll test with that. I had tried it previously with a CCA connected to a Samsung soundbar and had audio problems which were attributed ( perhaps incorrectly ) to soundbar shortcomings.

Hi @Tim_Jordan,

Question. That screenshot you put in this thread, is that from a portable MAC or a a iOS device?

I am asking this because I only get DSP Volume = passthrough on MAC. If I open the signal path on a iOS device I get “0.00db”.

Thank you

Hi @Pedro

I don’t own any Apple products.

The capture was made on my Windows 10 laptop. I have two Android tablets ( Amazon Fire HD 10 and Samsung Galaxy Tab S ) and I see the same Signal Path on them when playing to that CCA.


(Pedro Sousa) #75

Understood. Thank you. I think it’s some kind of bug with Roon on iOS. It does not identify the volume control as passthrough even though is set as that. But Roon in MAC OS shows it correctly.

Thanks again.

(Benjie Edmonson) #76

I can’t belive this is still going on! I’m on my second Roon trial and this is the only thing holding me up from buying in. I’m using toslink now with the cutouts. If I plug into my receiver using the provided 3.5mm I’m assuming my quality will go down??

(Mike) #77

@Benjie_Edmonson I’m not sure Roon are responsible. Quoting from above:

Do the CCA dropouts also happen on a 5GHz or wired (with optional adapter) network connection?

(Pedro Sousa) #79


On 5Ghz yes. Wired I have not tried. I did got the google version of the power supplier with Lan input. But I never tried it.
From reading Googles forums, it’s a bug from the beginning of the summer. Interestingly it does not affect all users, but the majority. and it’s irregular. sometimes it’s playing for 10 minutes without any issues and then you have a couple of dropouts suddenly. And it’s not repeatable.

My wifi is quite good. I get rates well above what one expect to need for sound.

(Derek Wyman) #80

Yes. No difference from my experience.

(Benjie Edmonson) #81

Exactly my experience.
I know this is not Roons fault. Just ready for Google to fix it. Otherwise great product.
