00871151 [James]all ringtone sounds intermittently for abou
發表於 : 2013年 4月 5日, 23:59
Step by step Description
1.Pair and connect BT headset with MUT.
2.Receive a MT call.-> Call ringtone is alerting.
3.Power off BT headset while call is ringing. ->Power on BT headset while call is ringing->Check the ringtone after BT headset is reconnected with MUT.
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Actual result
After step 3: Call ringtone sounds intermittently for about three seconds from MUT after reconnecting BTH during MT call ringing.
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Expect result
After step 3: Call ringtone should sound smoothly after BT headset reconnecting with MUT.
We want to know if there's any way to improve our audio quality while BT headset tries to connect MUT.
PS. We met a simular ringtone problem in Tapioca, and submit a case (00825224) before, not sure whether we can use the same solution while BT headset is connecting to MUT.
Thank you.

Dear Srinivas,
Sorry for my careless about changing wrong file.
After adding this line in AudioPolicyManager.cpp, the ringtone quality is improved a lot.
I will confirm with QA whether it's acceptable.
Thanks for your great support.

Dear Customer,
The file where changes are to be made are AudioPolicyManager.cpp and the file you have attached is AudioPolicyManagerBase.cpp.
AudioPolicyManager.cpp is in \hardware\qcom\media\audio\msm7627a.
Thanks,
Srinivas.

Dear Srinivas,
I check our code base, this line is already in AudioPolicyManager.cpp
Besides, our AudioPolicyManager.cpp is not in the path you said, it is in '\hardware\libhardware_legacy\audio'
Please refer to attachment for our AudioPolicyManager.cpp.
Could you please help to confirm whether the BSP we used are not the same?
Does this symptom not occur in your BSP?
Thank you.

Dear Customer,
Please add the following code in your file AudioPolicyManager.cpp(present in hardware\qcom\media\audio\msm7627a)
AudioPolicyManagerBase::checkA2dpSuspend();//Add the following line
Please see the code changes so that you can add the code.
Original Code.
#ifdef WITH_A2DP
AudioPolicyManagerBase::checkOutputForAllStrategies();
// A2DP outputs must be closed after checkOutputForAllStrategies() is executed
if (state == AudioSystem::DEVICE_STATE_UNAVAILABLE && AudioSystem::isA2dpDevice(device)) {
closeA2dpOutputs();
}
Modified code.
#ifdef WITH_A2DP
AudioPolicyManagerBase::checkA2dpSuspend();
AudioPolicyManagerBase::checkOutputForAllStrategies();
// A2DP outputs must be closed after checkOutputForAllStrategies() is executed
if (state == AudioSystem::DEVICE_STATE_UNAVAILABLE && AudioSystem::isA2dpDevice(device)) {
closeA2dpOutputs();
}
Please update the status of this issue.
Thanks,
Srinivas.

Dear Customer,
This issue is mainly because of the 2 following reasons.
1. The in band ringing is not supported in our phone. Hence we will just send the Ring indication to the headset. It is up-to the headset how it notifies.
2. Also our mobile takes only 3 seconds to get the ring indication after the BRSF is sent. This intermittent sound is heard for the first 3 seconds( We can also see that the SCO connection is not established). Whereas the competitor phone takes more than 12 seconds to get the Ring indication as a result this intermittent sound is not seen in the competitor phone.
This issue is mainly due to headset as it also needs to connect A2DP connection after restarting.( This SONY DS980 implements both HandsFree and A2DP functionality) Whereas this issue may not be seen in those headsets which implement only Hands free functionality.
Thanks,
Srinivas.

Dear Srinivas,
Do you mean the intermittent sounds is due to Qualcomm's solution is to emphasize the connection performance, so the audio quality has been impacted?
Competitor phone's connection performance is bad, it would not spend much resource to reconnect in a short time, so their audio sound would not be deffered.
Is my understanding of your comment right?
For this issue, we also verify on other referance phone, Sony Ericsson Arc, which uses Qualcomm 8225.
It does have the same issue too, but the intermittent sound is the signifcant as our phone.
We wonder if we could improve our audio quality as Arc, or is this a limitaion of 7267a?
Thank you.

Dear Customer,
We had a look at the logs and found that InBand Ringtone is not supported and hence we are only sending the ringtone indication and it is upto the headset that how it sends the ringtone.

If user is hearing intermittent ringtone on headset , it may be due to headset.
Also when we examined the behaviour with the a competitor phone we found that the issue was not reproducing, but the time taken to reconnect the headset after the headset is turned on is about 12 seconds in the competitor phone whereas it is about 3 seconds in our FFA.
Our FFA:
347 S (HF) 11 AT+BRSF=127. Retrieve AG Supported Features 27 00:00:12.570016 6/4/2012 10:21:20.302642 AM

//3.22 seconds is taken to connect back.

//12.63 seconds is taken to connect back.
And because of this increase in the time to reconnect the intermittent sounds of ringtone are not heard in the headset in the competitor phone.
Thanks,
Srinivas.

Dear Srinivas,
Upload the logcat, hcidump and OTA trace for this issue.
DS980 can reproduce this issue easily, the ringtone sounds intermittently while it reconnect to MUT.
BT620s almost can't reproduce this issue.
Please help to check the logs.
Thank you.
