As far as I know, alsa enables all of the controls which the card actually supports. If the card does not have an onboard "listening" channel (ie a connection internally from the record side to the output side) then alsa cannot enable it. And trying to send stuff out the sound card which collecting stuff is hard, especially if the connection is usb 1.1 ( low transfer rate). So why do you think that there are other options that alsamixer could enable? I suspect that the solution to your problem is to buy a better sound card. > > Thanks in advance. > Sebastian > > sudo aplay -l > aplay > > **** List of PLAYBACK Hardware Devices **** > card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 1: default [USB Audio CODEC ], device 0: USB Audio [USB Audio] > Subdevices: 0/1 > Subdevice #0: subdevice #0 > > > ------------------------------------------------------------------------------------------------------- > > sudo lsusb -v > lsusb > > http://pastebin.com/HzfSsG32 > > ------------------------------------------------------------------------------------------------------- > > tail -f /var/log/syslog > > Apr 1 20:31:17 sebas-laptop kernel: [ 5584.736783] usb 2-1.1: new full > speed USB device using ehci_hcd and address 6 > Apr 1 20:31:17 sebas-laptop kernel: [ 5584.832706] usb 2-1.1: > configuration #1 chosen from 1 choice > Apr 1 20:31:17 sebas-laptop kernel: [ 5584.844798] input: Burr-Brown from > TI USB Audio CODEC as > /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1/2-1.1:1.3/input/input18 > Apr 1 20:31:17 sebas-laptop kernel: [ 5584.845032] generic-usb > 0003:08BB:2902.0006: input,hidraw0: USB HID v1.00 Device [Burr-Brown from > TI USB Audio CODEC ] on usb-0000:00:1d.0-1.1/input3 > Apr 1 20:31:17 sebas-laptop pulseaudio[1654]: alsa-mixer.c: Your kernel > driver is broken: it reports a volume range from 0.00 dB to 0.00 dB which > makes no sense. > Apr 1 20:31:17 sebas-laptop rtkit-daemon[1454]: Sucessfully made thread > 3091 of process 1654 (n/a) owned by '1000' RT at priority 5. > Apr 1 20:31:17 sebas-laptop rtkit-daemon[1454]: Supervising 4 threads of 1 > processes of 1 users. > Apr 1 20:31:17 sebas-laptop pulseaudio[1654]: ratelimit.c: 31 events > suppressed > Apr 1 20:31:17 sebas-laptop rtkit-daemon[1454]: Sucessfully made thread > 3092 of process 1654 (n/a) owned by '1000' RT at priority 5. > Apr 1 20:31:17 sebas-laptop rtkit-daemon[1454]: Supervising 5 threads of 1 > processes of 1 users. > ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
