yo, hi all i found some old posts lying around in the archives mentioning support for hdsp rpm: http://sourceforge.net/mailarchive/message.php?msg_id=1107196346.10905.16.camel%40localhost (this was in january 2005) another one in august 2006: http://sourceforge.net/mailarchive/message.php?msg_id=7576529.1157023984118.JavaMail.www%40wwinf3203 i know at least two other people with the same card and they are actually using it under linux (and need a windows install in order to use it under linux) and both would be happy to see their card officially supported by alsa. i think, there is some interested for support around. if something can be done, i'd be glad to help. roman On Sun, 2007-12-09 at 00:26 +0100, Roman Haefeli wrote: > hi all > > i am a linux user since two years, but i've never managed to fully > support my rpm [1] box from rme. > > issue 1) > firmware > > in order to get the box running after pluging it to the power, i have to > boot windows, so that the correct firmware gets loaded. as long as the > box stays plugged to the power, i run linux and i can use the audio-box > under linux. however, i can use it only with some restrictions. when i > start 'hdspconf', the all the switches for multiface appear. i can > change some settings on the card, but i have to guess, which switch does > what. also, when i run 'hdsploader' it says: > > Card 1 : RME Hammerfall DSP + Multiface at 0x38000000, irq 4 > Upload firmware for card hw:1 > > it misrecognizes my box as a multiface instead of an rpm. also does the > hdspmixer show 18 input channels and 18 output channels instead of 6 > each (the first 6 sliders in the input and the output section work as > expected, though). > > i don't know how difficult it would be to add native support to alsa for > rpm as well. if it just a matter of no dev having such a box, i'd be > happy to deliver all information that is needed. i assume, making it > work cannot be so difficult, since it is technically already working, > but not officially supported. > > > issue 2) > > i cannot get the card run at higher rates than 48kHz. i tried with jack, > puredata and speaker-test and all of them print similar errors. someone > from #alsa suggested to try the 'plugin' plug instead of the 'hardware' > plug in order to use higher samplerates, but the 'plugin' plug doesn't > seem to work at all here. > > - puredata, 44100, hardware: > using mmap audio interface > requested channels=-1 but used=18 > playback device with 18 channels and buffer_time 46439 us opened > requested channels=-1 but used=18 > (works) > > > - puredata, 44100, plugin: > snd_pcm_hw_params (input): Invalid argument > snd_pcm_hw_params (input): Invalid argument > output snd_pcm_delay failed: Input/output error > astate 0 > audio I/O stuck... closing audio > (doesn't work) > > - puredata, 96000, hardware: > using mmap audio interface > requested channels=-1 but used=14 > error: Unable to set hw params: Device or resource busy > error: playback device hwparam_set error:: Device or resource busy > requested channels=-1 but used=14 > error: Unable to set hw params: Device or resource busy > error: capture device hwparam_set error:: Device or resource busy > error: could not link in and outs: File descriptor in bad state > error: outcard prepare error for playback: Input/output error > (doesn't work) > > - puredata, 96000, plugin: > snd_pcm_hw_params (input): Invalid argument > snd_pcm_hw_params (input): Invalid argument > output snd_pcm_delay failed: Input/output error > astate 0 > audio I/O stuck... closing audio > (doesn't work) > > - 'speaker-test -Dhw:1 -r 96000' > speaker-test 0.0.8 > Playback device is hw:1 > Stream parameters are 96000Hz, S16_LE, 1 channels > Using 16 octaves of pink noise > Access type not available for playback: Invalid argument > Setting of hwparams failed: Invalid argument > > my specs: > i am still running ubuntu dapper, which is quite old. i am using the > alsa-stuff from the repositories. i would like to compile alsa-drivers > (whatsoever is needed) myself, if necessary, but please don't just > advise me to reinstall everything without a particular reason. > > please also tell me, if you need some more information. > > not that i do understand much about alsa, but if i can, i'd be glad to > help to make the rpm working under alsa. i hope, this won't be too > complex, since it obviously uses the same architecture as the other hdsp > cards. > > [1] http://www.rme-audio.com/english/hdsp/hdsprpm.htm > > > roman > > > > > > ___________________________________________________________ > Der frhe Vogel fngt den Wurm.
