Hi there,

When casting Spotify from my phone, there are some songs that have very strange audio artifacts / blips present that are not present when playing them elsewhere. I play the songs through my phone's speakers, through a speaker system via an 1/8" stereo audio cable, in a car via an 1/8" stereo audio cable, and in a car via a bluetooth connection, and the blips are not present. Only while playing through my Chromecast do they appear.

They are only on certain songs, and they are always at the same place in the song every time I play them. Not sure if this could be an issue with Spotify's connection to Chromecast, or if it'd be an issue with the Chromecast, or a network issue. I tried using my wife's iPhone to cast the music and the issue persisted (exact same blips in the exact same songs). Here's a list of steps I've taken to troubleshoot this issue.

-Checked that both Android phone and iPhone had up-to-date operating systems and Spotify apps.

-I power cycled the Chromecast and made sure the software was up-to-date.

-There is a PC and a few gaming consoles plugged into the TV as well, and nothing like these blips ever occur with any content on the other devices.

-No other content sent to the Chromecast has this issue (YouTube, Netflix, Chrome browser tab, etc.).

-Tried a different Chromecast on a different TV in our house and the music has the same issues.

-Tried a Chromecast audio on a speaker system and the music does NOT have the blips.

-Removed the Spotify download for the affected songs, streaming them only - issue persisted. Re-downloaded songs, and issue still persisted.

Here is a video that shows one of the songs (Paperwhite - Human Nature) where the blips are the worst. They remind me of the old sound effect from a MacBook when the volume is changed.

For reference, here is the YouTube link for the song, which does not contain the blips:

This is a non-exhaustive list of other songs where I've noticed the blips. I'll update as I run across more:

Astrid S - "Hurts So Good - KREAM Remix"

Myzica - "We Belong Together"

AIRGLØW - "Dream"

Hillsong Young & Free - "In Your Eyes - Live" (right at the end)

Ella Vos - "Little Brother"
