2 channel to 7.1

[Blacknight]

Hi,
I have a 7.1 creative surround and with my macbook obviously I only have a 2 channel 3.5mm jack input for audio. Can I connect all the input channels in parallel for left and right seperately to drive from my 2 channel output? This are the specs for my sound card:

Jack type: 3.5 mm stereo
Maximum output voltage: 2 VRMS (+8.24 dBu)
Output impedance: < 24 Ω
Frequency response: 20 Hz to 20 kHz, +0.5 dB/-3 dB
Signal-to-noise ratio (SNR): > 90 dB
Total harmonic distortion + noise (THD+N): < -80 dB (0.01%)
Channel separation: > 75 dB

All 7.1 input impedance vary from 10K to around 22k with my DMM.
