Front Out (Channels 1/2) : Vol reg : Master, PCM 2. Rear Out (Channels 3/4) : Works only with "Alternate Level to Surround Out" set to [on] Vol reg : Headphone, PCM 3. Center/Sub Out (Channels 5/6) : Couldn't get sound at all. 4. Surround Out (Channels 7/8) : Works only with "IEC958" _not_ set to "PCM Out" Vol reg : PCM > Also, when you change the values in wm_inits[] in > snd_vt1724_amp_init(), especially, the values for WM_ATTEN_L and > WM_ATTEN_R to other values, say, 0x20 (-16dB), which outputs are > affected? > Recompiled modules with WM_ATTEN_L and WM_ATTEN_R set to 0x0020. Played some music. Unloaded original modules (/etc/init.d/alsasound stop) Replaced /lib/modules/2.6.18.6/alsa-driver Loaded newly compiled modules (/etc/init.d/alsasound stop) Played some music. All channels sounded the same.
