Mute controls work partially. VLC fails using the 5.1 mode of this device, too. b) tried extra config without affect (channels order wrong and center/lfe, rear sound low volume): schorpp@tom1:~$ grep ac3dec /etc/default/vdr OPTIONS="-a '/usr/bin/ac3dec -6 -D VIA8233.pcm.duplicate 2>> /var/log/vdrac3' -w60" #OPTIONS="-a '/usr/bin/ac3dec -6 -D CMI8738-MC6.pcm.duplicate 2>> /var/log/vdrac3' -w 60" #OPTIONS="-a '/usr/bin/ac3dec -D CMI8738-MC6.pcm.duplicate' -w 60" schorpp@tom1:~$ schorpp@tom1:~$ tom1:/home/schorpp# dpkg -l libasound2* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-===============-===============-============================================== ii libasound2 1.0.11-3 ALSA library ii libasound2-dev 1.0.11-3 ALSA library development files ii libasound2-doc 1.0.11-3 ALSA library developer documentation ii libasound2-plug 1.0.11-1 ALSA library additional plugins tom1:/home/schorpp# schorpp@tom1:~$ cat /proc/asound/* cat: /proc/asound/CMI8738MC6: Is a directory cat: /proc/asound/D3500: Is a directory cat: /proc/asound/V8235: Is a directory cat: /proc/asound/card0: Is a directory cat: /proc/asound/card1: Is a directory cat: /proc/asound/card2: Is a directory 0 [CMI8738MC6 ]: CMI8738-MC6 - C-Media PCI CMI8738-MC6 C-Media PCI CMI8738-MC6 (model 55) at 0xd800, irq 177 1 [V8235 ]: VIA8233 - VIA 8235 VIA 8235 with CMI9761 at 0xc800, irq 185 2 [D3500 ]: USB-Audio - DV 3500 DV 3500 at usb-0000:00:10.1-1, full speed 0: [ 0] : control 1: : sequencer 4: [ 0- 0]: hardware dependent 16: [ 0- 0]: digital audio playback 17: [ 0- 1]: digital audio playback 18: [ 0- 2]: digital audio playback 24: [ 0- 0]: digital audio capture 26: [ 0- 2]: digital audio capture 32: [ 1] : control 33: : timer 48: [ 1- 0]: digital audio playback 49: [ 1- 1]: digital audio playback 56: [ 1- 0]: digital audio capture 57: [ 1- 1]: digital audio capture 64: [ 2] : control 88: [ 2- 0]: digital audio capture 00-00: OPL3 FM 0 snd_cmipci 1 snd_via82xx 2 snd_usb_audio cat: /proc/asound/oss: Is a directory 00-02: CMI8738-MC6 : C-Media PCI IEC958 : playback 1 : capture 1 00-01: CMI8738-MC6 : C-Media PCI 2nd DAC : playback 1 00-00: CMI8738-MC6 : C-Media PCI DAC/ADC : playback 1 : capture 1 01-01: VIA 8235 : VIA 8235 : playback 1 : capture 1 01-00: VIA 8235 : VIA 8235 : playback 4 : capture 1 02-00: USB Audio : USB Audio : capture 1 cat: /proc/asound/seq: Is a directory G0: system timer : 4000.000us (10000000 ticks) P0-0-0: PCM playback 0-0-0 : SLAVE P0-0-1: PCM capture 0-0-1 : SLAVE P0-1-0: PCM playback 0-1-0 : SLAVE P0-2-0: PCM playback 0-2-0 : SLAVE P0-2-1: PCM capture 0-2-1 : SLAVE P1-0-0: PCM playback 1-0-0 : SLAVE P1-0-1: PCM capture 1-0-1 : SLAVE P1-0-2: PCM playback 1-0-2 : SLAVE P1-0-4: PCM playback 1-0-4 : SLAVE P1-0-6: PCM playback 1-0-6 : SLAVE P1-1-0: PCM playback 1-1-0 : SLAVE P1-1-1: PCM capture 1-1-1 : SLAVE P2-0-1: PCM capture 2-0-1 : SLAVE Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC). schorpp@tom1:~$ ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 05-26-06 20:24 schorpp New Issue 05-26-06 20:24 schorpp Distribution => debian sarge...sid 05-26-06 20:24 schorpp Kernel Version => 2.6.16.18 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
