troubleshooting audio quality issues in sweden

Postby rika » Wed Dec 05, 2012 10:26 am

this is in reference to a previous post + a chat i had in the irc channel (discussion-and-questions/10-second-audio-delays-in-europe-t14331)

basically we have a client in stockholm whose sessions seem to not be getting set to the london opentok servers (and so they are having extreme quality issues).

here are some IssueId's from various tests:

no location hint passed in, 2 users connect from stockholm, p2p disabled: 52EC9F311EEE94D4B60F8DBCC62D1921 (session id: 1_MX4yMTM0MjE5MX5-V2VkIERlYyAwNSAwMzoyODo1NSBQU1QgMjAxMn4wLjgxMjE1NDM1fg)

location hint passed in, 1 user connects from nyc, p2p disabled: B09A19C5EFA5CFB1F8AA36829DDE891B (session id: 2_MX4yMTM0MjE5MX4yNC4xOTMuNjYuNzJ-V2VkIERlYyAwNSAwNjo1MzowNSBQU1QgMjAxMn4wLjE4MDcwMDI0fg)

location hint passed in, 2 users connect from stockholm, p2p disabled: 2974953B1CE3D8E44FBF70C21768F821 (chrome) 034BD0A7C6C7CAD6FDEA97EC6DDD9D3D (safari) (session id: 2_MX4yMTM0MjE5MX44MS4yMjkuODIuMTYwfldlZCBEZWMgMDUgMDc6MTM6MjcgUFNUIDIwMTJ-MC41MDgwMTU1fg)

(i also tried to have them do a session that was p2p, but i can't verify that a new session id was actually created for this test... :oops: but just to be complete, here are two issue id's from that test: 32811DC05FC86E371292B5C797322415 and CB45F7DE829D99DD64BADF549310AAD6)

the client recorded audio samples which i can upload if necessary.

thanks for any help!

Hi there. It seems like some of the connections were indeed going to london servers. Have you tried using firefox? Chrome on Mac OSX has some problems with audio right now.

i can recommend that they try using firefox... i verified that the robot voice issue was only occurring on chrome. any idea when that will be fixed?

is there any other info you can provide me? perhaps you could tell me which issue id went to which server so i can figure out which change made it work? i'm confused by the documentation that says "if you don't provide a location hint, the server location will be chosen by the ip address of the first user to connect"... so for the first session listed, this should still have chosen the london servers, did it?

i'm also attaching a file that shows audio dropping in/out (the client counts from 1 to 15 and some numbers cut out). any thoughts on troubleshooting this?

thanks

The only session that connected to new york was "B09A19C5EFA5CFB1F8AA36829DDE891B". The other two connected to london. Can you verify that the audio dropping in and out still happens when they use firefox?

As for the chrome fix, it is chrome's bug. They have stated that they are pushing out a patch possibly next week.

The audio may also be due to chrome 23. Could you see if audio drops out without anyone using chrome 23?
