I applied this patch :

http://linuxtv.org/hg/v4l-dvb/rev/360a5196177c

and it fixed my tuner sound problem. The exact line that fixed the issue 
is this one :

+
+ /* unmute audio source */
+ cx_clear(AUD_VOL_CTL, (1 << 6));
blackbird_api_cmd(dev, CX2341X_ENC_MUTE_VIDEO, 1, 0, BLACKBIRD_UNMUTE);
msleep(1);
blackbird_api_cmd(dev, CX2341X_ENC_MUTE_AUDIO, 1, 0, BLACKBIRD_UNMUTE);
msleep(1);
