This issue does NOT occur on Flame 3.0

Dial tone sounds are played without any disruption

[Johan Lorenzo [:jlorenzo]]

[Blocking Requested - why for this release]: Regression from the Flame.

Comment 3

[Jean Gong :jgong]

[Blocking Requested - why for this release]:

Spark triage team decided that this bug is not a Spark blocker: moving this to 3.0?

Comment 4

[Paul Adenot (:padenot)]

This is very likely to be underruns cause by the fact that the latency is too low and Web Audio API is too expensive for now.

I think we trigger the opensl fastpath in cubeb with this device (z3c), and not in the flame.

Comment 5

[Johan Lorenzo [:jlorenzo]]

Comms triage: Will break the experience on Z3C.

Comment 6

[Maire Reavy [:mreavy]]

I think it makes sense to re-test this since a lot of changes have landed since May.

Moving this one back to Dialer since this problem doesn't occur on Flame 3.0.

Comment 7

[Mahendra Potharaju [:mahe]]

[Blocking Requested - why for this release]: Nominating for 2.5 as it needs to be re-verified.

Comment 8

[Jayme Mercado [:JMercado] (Inactive 3/4/2016)]

Checking this issue is blocked by bug 1201133.  Once that is resolved we can check this issue again.

Comment 9

[Johan Lorenzo [:jlorenzo]]

Comms triage: Even with bug 1201133 being here, you can here some static noise at the first dial tone.

Comment 10

[Martin Shuman [:Marty]]

This issue is still occurring on the latest Spark Aries 2.5 build.
Static can be heard in the dialer touch tones.

[Gabriele Svelto [:gsvelto]]

I am unable to reproduce this because I'm encountering another problem: only the first touchtone is audible, all following ones are muted. I seem to have seen a similar bug but I can't find it anywhere, Alastor can you help me out finding it?

Comment 12

[Alastor Wu [:alwu][PTO, back on 12/15]]

We have a similar issue that the built-in keyboard only has first audible sound (bug1183033), but this issue seems not equal to bug1183033. 
After applying the patch of bug1183033, this issue still exists.

Comment 13

[Alastor Wu [:alwu][PTO, back on 12/15]]

Ah, we had the bug1201133 before, and the bug1183033 can fix it at that time (but can't fix it now).

Comment 14

[Gabriele Svelto [:gsvelto]]

Thanks Alastor, I'll try running a bisection to figure out what broke this since it used to work just a few weeks ago.

Comment 15

[Gabriele Svelto [:gsvelto]]

[Blocking Requested - why for this release]: I'd like to de-nom this bug because it's impossible for me to reproduce it because of bug 1211105. BTW this is most likely not a dialer bug since the relevant code hasn't been touched in months but rather an issue somewhere within gecko.

Comment 16

[Johan Lorenzo [:jlorenzo]]

I tested it again on [1] and even though you have 1 dial tone, you can hear static in there.

Comms triage: Regression from 2.2. Agreed with the fact that it's more a gecko related issue.

Not a dialer issue though, not sure if this should be moved to Core::Web Audio or Firefox OS::Audio Channel.

Comment 18

[Gabriele Svelto [:gsvelto]]

Moved to Core::Web Audio, please reassign if this is not the right component.

Comment 19

[Maire Reavy [:mreavy]]

Paul -- can you look at this?  Thanks.

Comment 20

[Paul Adenot (:padenot)]

The z3c has issues at the gonk level that we need to fix first. For example bug 1166758. Lollipop might solve it, so we're blocked on that.

Comment 21

[Maire Reavy [:mreavy]]

Reading over Bug 1166758, it looks like the root cause of this bug may be identical to the root cause for Bug 1166758.  Rather than dup'ing this bug to Bug 1166758, I'm marking this as blocked by it so that we come back to this bug and re-test once Bug 1166758 is resolved.

I'm marking QA-wanted to ask QA to re-test this once Bug 1166758 is resolved.  If it's not, we'll take another look.

Comment 22

[Maire Reavy [:mreavy]]

New info: Paul Adenot retested this today because he observed bug 1166758 seems to have been fixed by the latest the last OTA update (see bug 1166758 for that discussion).  However, during his retest, he discovered a new regression and opened bug 1214195 (Dialer only makes one tone when dialing a number).  I've made that new bug a P1 and nominated it as a 2.5 blocker.  It's possible that this bug was resolved by the OTA update (like bug 1166758), but we won't know until bug 1214195 is resolved.

It's not new. Comment 8 already had the bug number for that issue.

Comment 24

[Maire Reavy [:mreavy]]

Reviewing the B2G priority (P1, P2, P3) definitions, this bug is a "P3" bug.  This doesn't impact dogfooding or prevent using the phone.  It's simply glitchy, and we want to fix it.

Comment 25

[Dylan Oliver [:doliver]]

triage: unblocking this for 2.5, there is no effect on usage.

Comment 26

[Paul Adenot (:padenot)]

I not planning on working on this, but ping me if you need to chat.

Comment 27

[Bulk Bug Changes for mreavy's org]

Mass change P3->P4 to align with new Mozilla triage process.

Comment 28

[Sylvestre Ledru [:Sylvestre]]

Closing bugs with b2g-master=affected as it is likely to be out dated.
