I have a function which generates multiple sweep generator and it looks like this:

function [x, xinv,y_m]=genmesm_far(fs,T,f_start,f_end,A,L1,L2,tau_2) %Multiple exp. Sweepgenerator. x_m = A*sin(W1*siglen_MESM/log(W2/W1).*(exp(((0:siglen_MESM)./siglen_MESM)*log(W2/W1))-1)); %Multiple Sine Sweep

 imax=5;
     t = delay (imax,e, L1 ,tau_k);
     t_max=max(t);
    x = zeros(length(x_m)+t_max+fs,imax);
     for n = 1:imax
      x(:,n)     = [zeros(t(n)+fs,1);x_m';zeros(t_max -t(n),1)];
     end
       x1      =  x(:,1);
       x2      = x(:,2);
       x3      = x(:,3);
       x4      = x(:,4);
       x5      = x(:,5);
       y_m = x1+x2+x3+x4+x5;% Simulated Measurement
       y_m=y_m';

I need to play x1 to X5 and record it..I am using digital audio toolbox: The code below looks like this: s = daq.createSession('directsound'); %create session s.DurationInSeconds =7 ; %duration; s.UseStandardSampleRates = true; s.Rate = fs;

devs = daq.getDevices; %list audio devices in system
 [ch12, idx12] = addAudioOutputChannel(s,devs(22).ID,1:2); %balancedlineoutput_1&2
 [ch34, idx34] = addAudioOutputChannel(s,devs(18).ID,1:2); %balancedlineoutput_3&4
 [ch56, idx56] = addAudioOutputChannel(s,devs(15).ID,1:2); %balancedlineoutput_5&6
   queueOutputData(s, [x1 x2 x3 x4 x5 x1]); 
   startBackground(s);
My question is how can I play all these output from x1 to x5 in a loop in the function audioplayer 
 nBits = 24;
playOBJ = audioplayer(x1,fs,nBits,22); 
recOBJ = audiorecorder(fs,nBits,2,-1);
%play(playOBJ);
recordblocking(recOBJ,5.1*length(x1)/fs);
 recordedData = getaudiodata(recOBJ, 'double');   
recordedData1 = recordedData(:,1);
recordedData2 = recordedData(:,2);
