Hello, I am new on this, I have a little problem with my HTPC sound configuration. I search a lot and I don't have the solution. I have a Nvidia ION based HTPC. I have connected with optical to the A/V receiver (Sony STR-DG710). The HD movies with "good" audio sounds great and on the receiver puts "DOLBY DIGITAL 3/2.1", but when I play a MP3 file sounds very bad, with noise, and on the receiver puts ?PCM 48 kHz?. This is my audio configuration: $ cat /proc/asound/cards 0 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xfae78000 irq 20 $ cat /proc/asound/pcm 00-01: ALC662 Digital : ALC662 Digital : playback 1 00-00: ALC662 Analog : ALC662 Analog : playback 1 : capture 1 I use Debian Lenny and I installed PulseAudio from official repository. When I run PulseAudio Manager this the configuration: http://img257.imageshack.us/img257/9110/pantallazopulseaudioman.png<http://img257.imageshack.us/i/pantallazopulseaudioman.png/> http://img29.imageshack.us/img29/9110/pantallazopulseaudioman.png<http://img29.imageshack.us/i/pantallazopulseaudioman.png/> http://img29.imageshack.us/img29/9766/pantallazopulseaudiomany.png<http://img29.imageshack.us/i/pantallazopulseaudiomany.png/> http://img518.imageshack.us/img518/9110/pantallazopulseaudioman.png<http://img518.imageshack.us/i/pantallazopulseaudioman.png/> http://img518.imageshack.us/img518/5256/pantallazopulseaudiomanp.png<http://img518.imageshack.us/i/pantallazopulseaudiomanp.png/> They are empty, how I must configure?
