[alsa-devel] S51 usb support

Daniel, you are right, Its the driver thing. Feb 2009, I was dealing this the same issue and James Courtier-Dutton from this list pointed out that the device has no hardware based mixer controls which is why alsamixer does not find anything. He suggested using SoftVol. I've been using dmix and Softvol for volume control whenever I need it. This is the ~/.asoundrc I use http://mndar.phpnet.us/usbxfi/files/asoundrc.log The device has a volume knob. I had left the issue of the volume knob alone until a few days back.. I was about the post this when I came across the query from Matti Picus. This is how it works. The volume knob sends an interrupt via endpoint 0x83 containing 0xC0 0x00 whenever it is rotated clockwise,anti-clockwise or pressed. After this a control message is sent to the device to retrieve which of the 3 actions it was. The control packet sent is 0xa1 0x85 0x00 0x00 0x00 0x00 0x04 0x00 We get a 1 byte response. 0x0F for anti-clockwise rotation. 0x0D for press and 0x10 for clockwise rotation. I've tested this using a simple kernel module to handle just the volume knob and it works fine. The quick little code I've written does the above, then sets a sysfs attribute and sends a kobject_uevent. Udev rules execute a command depending on the value of this sysfs attribute. (Having some issues here but anyway...) Since the volume is entirely a software thing, I figure this might be a good way of letting userspace know about the volume knob. Using softvol we can have a Master volume control and then we can use a command like amixer in udev rules to change the volume. Or since events are passed to HAL, something could be done there. I do not know much about the usbaudio driver but does this seem like something that can be done from within the usbaudio driver ? -Mandar Joshi

Or you can put my address directly to Cc. Otherwise I'll have to look down to alsa-devel ML folder, and the posts are even sometimes delayed due to non-subscribers filtering... thanks, Takashi

[alsa-devel] RME MADIface 192 kHz problem
by Fredrik Lingvall 23 Oct '10

23 Oct '10

Hi all, I have a problem running the RME MADIface card at 192 kHz. At that speed the number of channels for the card is reduced to 16. I can set the sampling rate to 192 kHz using: # amixer -c 1 cset numid=2 9 numid=2,iface=MIXER,name='Sample Clock Source' ; type=ENUMERATED,access=rw------,values=1,items=10 ; Item #0 'AutoSync' ; Item #1 'Internal 32.0 kHz' ; Item #2 'Internal 44.1 kHz' ; Item #3 'Internal 48.0 kHz' ; Item #4 'Internal 64.0 kHz' ; Item #5 'Internal 88.2 kHz' ; Item #6 'Internal 96.0 kHz' ; Item #7 'Internal 128.0 kHz' ; Item #8 'Internal 176.4 kHz' ; Item #9 'Internal 192.0 kHz' : values=9 but when I try to read data at 192 kHz I always get a : Invalid argument from the snd_pcm_hw_params_set_channels(...) and snd_pcm_hw_params(...) functions when I try to set the number of channels. The snd_pcm_hw_params_get_channels_max(...) snd_pcm_hw_params_get_channels_min(...) functions also seems to return the wrong number of max and min number of channels. And, jackd will not start using 192 kHz. See the thread here: http://www.rme-audio.de/forum/viewtopic.php?id=9169 What is needed to get this card running at 192 kHz?
