I searched using tag: "parse_audio_format_rates_v2" I don`t know if they are suitable for me. Several patches were suggested for them from ALSA developers. I tryed to search the resolve of the problem in the internet, and I found there are several devices that people tryed to use and got the same message. ALSA format.c:284 parse_audio_format_rates_v2(): unable to find clock source (clock -71) usb 1-3: new high-speed USB device number 5 using ehci_hcd When I plug my device in usb port:ħ9.246940] usb 1-3: USB disconnect, device number 2 I add some extra info from my system about this device. So device is specific, nobody gave me the info how to resolve the problem with the audio. I tryed to discuss about my problem on #alsa chanell on but only several people agreed to answer on my questions. Software: Archlinux x86-64, stock 3.6.10 and manually compiled 3.7.1 kernels, ALSA 1.0.25Īttachments: ( from lsusb -v) My Laptop CPU: Turion64x2 TL-62, 2GB RAM, VPU: Radeon 2600Pro 512mb, build in Audio Card Realtec ALC268.ĭJ midi-controller: Hercules DJ Console RMX2 with buildin audio card(it seems on the base of Xmos chip) I even dont know where I can write about this problem to and get support. I don t want to use Windows and such software as Traktor and etc, I prefer quickly working linux OS and optimized for my laptop fresh Mixxx release from the sources. Anyway if somebody can help me (it seems not only me) please, give your recommendetions how to resolve the problem with the soundcard and may be anybody of developers has mapping for RMX2. The problem may be resolved by adding such support in alsa-driver or may be firmware from Xmos(if used chip is Xmos made really) to alsa-firmware. I tryed to search the solving of that problem, I found that problem may be connected with such item that there is no full support of UAC2 in alsa. When I try to admine the sound card I get the error from ALSAMIXER: "Protocol error". It seems it uses Xmos DSP chip to work with audio. The sound card is detected by UDEV and described in the system. I use ALSA (v.1.0.25) to work with audio devices in my system. It seems that buildin high quality sound card doesnt support. When I reboot my laptop, and try to work ith Mixxx again, so Kernel panic may be appear sometimes again. Nevertheless when I tryed to play on it in Mixxx, I got kernel panic(I use Archlinux x86_64, linux kernel 3.6.10). I tryed to do this manuality, using Learning Wizard, but the mapping I got is not full. I connect the device to the PC, start Mixxx 1.11(compiled from trunk), the device is detected as midi-compatible, but there is no layout for this controller. This device uses MIDI protocol to send commands to Mixxx(not Bulk as vendor s previous devices ). Hello! I bought a new midi controller Hercules DJ Console RMX2. It describes USBMixer of the RMX2s sound card), ( from lsusb -v), snd_usb_audio_rmx2.patch, snd-usb-audio-rmx2-dkms_0.10_all.deb, snd-usb-audio-rmx2-dkms_0.11_all.deb, snd-usb-audio-rmx2-dkms_0.12_all.deb
