Why the playback failed

Solution:

Modified files: 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;}

If the load thread is not ready sample->state ()! = Sample::ready, wait for 2.25s to play again
