Hi, I’m trying adding support for Creative SB1240(Sound Blaster HD, USB DAC).. Player Volume control is working like a charm, but.. “Capture” interface (Mic, Line, Phonograph) – not working at all. Can you help me to add support for this card? I’m trying to sniff USB traffic between USB DAC & Windows Driver(with Wireshark usbdump). But.. I need more theory, to do it.. I cannot get work any capturing interface ☹ I’t my environment: # uname -a Linux kernel 4.9.20 #1 SMP Wed Apr 5 18:42:37 MSK 2017 x86_64 GNU/Linux # cat /etc/group audio:x:63:root # dmesg *************** [ 1.670745] usb 1-1.1: New USB device found, idVendor=041e, idProduct=3232 [ 1.670748] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1.670750] usb 1-1.1: Product: USB Sound Blaster HD [ 1.670752] usb 1-1.1: Manufacturer: Creative Technology [ 1.670753] usb 1-1.1: SerialNumber: 000003II [ 1.673435] input: Creative Technology USB Sound Blaster HD as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.5/0003:041E:3232.0001/input/input6 *************** # ls -la /dev/snd/ total 0 drwxr-xr-x 4 root root 220 Apr 5 21:33 . drwxr-xr-x 15 root root 3360 Apr 5 21:34 .. drwxr-xr-x 2 root root 60 Apr 5 21:33 by-id drwxr-xr-x 2 root root 60 Apr 5 21:33 by-path crw-rw---- 1 root audio 116, 2 Apr 5 21:33 controlC0 crw-rw---- 1 root audio 116, 4 Apr 5 21:33 pcmC0D0c crw-rw---- 1 root audio 116, 3 Apr 5 21:34 pcmC0D0p crw-rw---- 1 root audio 116, 6 Apr 5 22:57 pcmC0D1c crw-rw---- 1 root audio 116, 5 Apr 5 21:33 pcmC0D1p crw-rw---- 1 root audio 116, 7 Apr 5 21:33 pcmC0D2p crw-rw---- 1 root audio 116, 33 Apr 5 21:33 timer # amixer info Card default 'HD'/'Creative Technology USB Sound Blaster HD at usb-0000:00:1a.0-1.1, full speed' Mixer name : 'USB Mixer' Components : 'USB041e:3232' Controls : 8 Simple ctrls : 2 # amixer contents numid=6,iface=MIXER,name='PCM Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=7,iface=MIXER,name='PCM Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=128,step=0 : values=128,128 | dBminmax-min=-64.00dB,max=0.00dB numid=8,iface=MIXER,name='PCM Capture Source' ; type=ENUMERATED,access=rw------,values=1,items=3 ; Item #0 'Mic' ; Item #1 'Line' ; Item #2 'Phonograph' : values=1 numid=4,iface=PCM,name='Capture Channel Map' ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR numid=1,iface=PCM,name='Playback Channel Map' ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=3,4 | container | chmap-fixed=FL,FR numid=5,iface=PCM,name='Capture Channel Map',device=1 ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR numid=2,iface=PCM,name='Playback Channel Map',device=1 ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR numid=3,iface=PCM,name='Playback Channel Map',device=2 ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR С уважением, Александр Самохин Заместитель начальника отдела Отдел информационных технологий и компьютерного обеспечения ФГУП «Большой Московский цирк» Email: a.samokhin(a)greatcircus.ru<mailto:a.samokhin@greatcircus.ru> , it(a)greatcircus.ru<mailto:it@greatcircus.ru> Tel: +7 (495) 930-22-25, вн. 2002 Mob: +7 (903) 296-77-98

[alsa-devel] [PATCH 1/2] plugin:dshare: wrong state reporting
by sutar.mounesh＠gmail.com 05 Apr '17

05 Apr '17

From: Andreas Pape <apape(a)de.adit-jv.com> If plugin dshare detects underrun, it reports this to the user via return value -EPIPE and setting dshare state to 'xrun' which is correct. But, if user after this wants to check the stream state, it is misleadingly reported as 'running' instead of 'xrun'. With this behavior aplay e.g. will not do a proper underrun handling (restarting stream) but terminates streaming. This is due to plugin dshare always returns state of the slave pcm, in pcm_ops->state() which is not correct.

[alsa-devel] [PATCH] ALSA: firewire-lib/bebob/oxfw: improve response evaluation for AV/C commands
by Takashi Sakamoto 05 Apr '17

05 Apr '17

In ALSA firewire stack, some AV/C commands are supported, including vendor's extensions. Drivers includes response parser of each command, according to its requirements, while the parser is written with loose fashion in two points; error check and length check. This doesn't cause any issues such as kernel corruption, but should be improved. This commit modifies evaluations of return value on each parsers.

[alsa-devel] [PATCH] ALSA: firewire-motu: remove invalid bitshift for register value
by Takashi Sakamoto 05 Apr '17

05 Apr '17

In protocol version 3, drivers can read current sampling clock status from register 0x'ffff'f000'0b14. 8 bits of LSB of this register represents type of signal as source of clock.

[alsa-devel] [PATCH] ALSA: oxfw: fix regression to handle Stanton SCS.1m/1d
by Takashi Sakamoto 05 Apr '17

05 Apr '17

At a commit 6c29230e2a5f ("ALSA: oxfw: delayed registration of sound card"), ALSA oxfw driver fails to handle SCS.1m/1d, due to -EBUSY at a call of snd_card_register(). The cause is that the driver manages to register two rawmidi instances with the same device number 0. This is a regression introduced since kernel 4.7. This commit fixes the regression, by fixing up device property after discovering stream formats.

[alsa-devel] [PATCH 0/4] ALSA: firewire-digi00x: integration to support console models
by Takashi Sakamoto 05 Apr '17

Hi, Disidesign Digi00x series includes two types of unit; rack and console. ALSA Digi00x driver is originally designed to handle both types. Recently I got console model and realized that it can't handle console type, as a result of packet sniffing. This patchset is to add proper support for unit of the console type, with new information from the reverse-engineering work.

[alsa-devel] [PATCH 00/14] ALSA: fireface: new driver for RME Fireface series
by Takashi Sakamoto 05 Apr '17

05 Apr '17

Hi, This patchset updates my previous RFCv3, and go for ALSA upstream. [alsa-devel] [RFC v3][PATCH 00/13] ALSA: fireface: new driver for RME Fireface series http://mailman.alsa-project.org/pipermail/alsa-devel/2017-February/117811.h… This patchset newly adds a driver into ALSA firewire stack, to support for Fireface 400 in RME FireWire series. Unfortunately, units on this series are completely against IEC 61883-1/6. This brings much commits and descriptions into this patchset. I'd ask you to review much amount of codes, as well as MOTU FireWire series, to finish my work for AMDTP variants[0]. As I noted to my former patchset, units of the series have unique feature; resampling between packet/data block processing layer and sample processing layer. This patchset relies on this layer, in short the driver doesn't handle sampling clock frequency, just handle sampling transmission frequency and expects units to generates audio from resampled data. Users should use proper application to configure sampling clock frequency when they want to match the frequency and sampling transmission frequency. Changes from RFCv3: * Add function pointer to AMDTP structure to reduce branching on packet processing. * Improve commit description.
