Caps Plate2x2 differences between Arch/Debian

by James Morris

Has anyone else come across this issue with the LADSPA Caps Plate plugin with the effect on Arch being very much reduced compared with the amount of effect provided by the same plugin in Debian? With the plugin tail and bandwidth set to maximum, damping at a minimum, and no dry effect, silence arrives in a flash. Its a problem I've noticed for several months... James.

HDSP wrong firmware gets loaded (digi- vs multiface)

by Peter P.

Hi list, hdsploader (via hotplug) on my box seems to load firmware at will. Sometimes it loads the Digiface firmware into my Multiface, sometimes it loads the correct one. I suppose I could simply delete the digiface firmware from the path, but what is it that makes it load the wrong one? correct one: kernel: [98033.160982] pci 0000:05:00.0: BAR 0: assigned [mem 0xf0000000-0xf000ffff] kernel: [98033.161012] pci 0000:05:00.0: no hotplug settings from platform kernel: [98033.161264] snd_hdsp 0000:05:00.0: enabling device (0000 -> 0002) kernel: [98033.467674] Hammerfall-DSP: wait for FIFO status <= 0 failed after 30 iterations kernel: [98033.474630] snd_hdsp 0000:05:00.0: firmware: agent loaded multiface_firmware_rev11.bin into memory wrong one: kernel: [98146.327251] Hammerfall-DSP: loading firmware kernel: [98149.392459] Hammerfall-DSP: finished firmware loading kernel: [98243.384790] pci 0000:05:00.0: BAR 0: assigned [mem 0xf0000000-0xf000ffff] kernel: [98243.384824] pci 0000:05:00.0: no hotplug settings from platform kernel: [98243.385118] snd_hdsp 0000:05:00.0: enabling device (0000 -> 0002) kernel: [98243.689751] snd_hdsp 0000:05:00.0: firmware: agent loaded digiface_firmware_rev11.bin into memory Does someone else have the same issue? best, P

Strange change of sample rate upon connecting mixing desk

by Peter P.

Dear list, allow me to post a question here that I already sent to alsa-user, but without any response so far, thank you! ----------8<----------- Hi all, now here is one of the weirdest problems I have come across in the past years. Actually it is halting my current production even, but I am primarily interested how this error is caused (and how it can be solved): The sampling rate of my RME HDSP Card is set from "Internal 44.1k" to "Internal 48k" upon connecting a Yamaha DM1000 mixing console via usb! The console does not provide a USB audio interface, but several midi ports over USB, using the snd_usb_audio module. cat /proc/asound/cards: 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xf2520000 irq 43 1 [DSP ]: H-DSP - Hammerfall DSP RME Hammerfall DSP + Multiface at 0xf0000000, irq 19 2 [DM1000 ]: USB-Audio - DM1000 Yamaha DM1000 at usb-0000:00:1d.0-1.2, full speed 29 [ThinkPadEC ]: ThinkPad EC - ThinkPad Console Audio Control ThinkPad Console Audio Control at EC reg 0x30, fw 6QHT26WW-1.07 >From HDSP's alsamixer I can see that upon connecting the DM1000 the control "Sample Clock Source Locking" gets set to [Off], and the sample rate is set to 48k as described above. The change is also reflected in the 'hdspconf' software that configures some properties of the card. cat /proc/asound/pcm does not list the DM1000: 00-00: CONEXANT Analog : CONEXANT Analog : playback 1 : capture 1 00-03: HDMI 0 : HDMI 0 : playback 1 01-00: RME Hammerfall DSP + Multiface : RME Hammerfall DSP + Multiface : playback 1 : capture 1 This is on a Debian box runnig kernel 3.2.0-4-rt-amd64 Let me add here, that upon starting any audio application using the same card under alsa can (re)set the sampling rate to the correct value. If the mixer is re-connected, after that audio application was launched, the sampling rate of the HDSP card is changed to 48k, causing an audible transposition. Can anyone imagine what causes this strange behavior? Thank you so much for all hints best, P
