Why the playback failed

How to resolve:

Change file: Frameworks/av/media/libmedia/soundpool.cpp

int Soundpool::p Lay (int sampleid, float leftvolume, float rightvolume, int priority, int loops, float rate) {ALOG V ("Play sampleid=%d, Leftvolume=%f, rightvolume=%f, priority=%d, loop=%d, rate=%f", SampleID, Leftvolume, right    Volume, priority, loops, rate);    Sp<sample> Sample;    soundchannel* Channel;    int channelid;    Mutex::autolock Lock (&mlock);    if (mquit) {return 0; }//Is the sample ready?

Sample = Findsample (SampleID); 2015.06.06 Add for BEGIN if (sample! = 0) {int loopcounter = 15; while (loopcounter--> 0 && (sample->state ()! = Sample::ready)) {alogd ("Wait for the sample ready, SLE EP 150ms "); Usleep (150 * 1000); }}//2015.06.06 add for End if ((sample = = 0) | | (Sample->state ()! = Sample::ready)) {ALOGW ("Sample%d not Ready", SampleID); return 0; } dump (); Allocate a channel Channel = allocatechannel_l (priority); No channel Allocated-return 0 if (!channel) {ALOGV ("no channel allocated"); return 0; } Channelid = ++mnextchannelid; ALOGV ("Play channel%p state =%d", channel, Channel->state ()); Channel->play (sample, Channelid, Leftvolume, Rightvolume, priority, loops, rate); return channelid;}

Assume that the onboarding thread is not ready to sample->state ()! = Sample::ready. Wait for 2.25s to play again
