AC3 passthrough is completely broken. My hardware: NVidia GT430, hdmi output Device used: hdmi:CARD=NVidia,DEV=0,AES0=6,AES1=0x82,AES2=0x00,AES3=0x01 on Ubuntu 10.04 LTS (but using manually built alsa) It makes the application hangs or behaves incorrectly. All the time broken, no matter which app. Reverting back to 1.0.24 fixes the problem I haven't delved much into it yet, MythTV (I am the audio developer) after opening the audio device in passthrough mode, trying to write audio on the pcm just hangs and result in an I/O error after a little while snd_pcm_writei returns an error (not immediately) snd_pcm_state(pcm_handle) returns 3, snd_strerror(err) returns "Input/output error" mplayer just hangs... nothing obvious in the logs, audio device opens okay, i can't say I notice much difference in opening the device, allocating fragment and the lot. Anyone else has seen this? Jean-Yves
