When "IEC958 Default PCM" is set to on, the analog PCM outputs are also routed to the digital output automatically. So you should be hearing the sound played via aplay. The "iec958" PCM device is for the exclusive digital output, mainly for the raw digital stream like AC3. If it's being used with the analog streams at the same time, you won't be able to open it. BTW, I found why model=auto doesn't work well on your machine. It's because (again) of BIOS. It doesn't set the codec SSID properly so the driver doesn't accept the HP auto-toggle and other features. So, in your case, using model=acer-aspire would be likely the best choice (supposing it matches with most functionality). If you have no problem (at least regressions) with this model, I'll add the entry to point to model=acer-aspire Anyway, my previous test patch is independent from the model problem. It's still helpful to know whether it can solve the codec communication errors with model=auto. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
