Should changes in "channel mode" , "Headphone Mic jack mode" or "Mic Jack Mode" trigger an event so that pulseaudio server probe the sound card again ? There is still bug in the patch should check (cfg->line_out + spec->multi_ios) >= 3 instead of spec->multi_ios > 0 so that the channel mode is not added for notebook with line out and mic jack -------------- next part -------------- An HTML attachment was scrubbed...
