The post below generated no response on the developers list - maybe someone here could point me in the right direction? ---------- Forwarded message ---------- From: Adrian McMenamin <lkmladrian@xxxxxxxxx> Date: 2008/12/29 Subject: Fixing the AICA driver To: alsa-devel <alsa-devel@xxxxxxxxxxxxxxxx> Cc: Adrian McMenamin <adrian@xxxxxxxxxxxxxxxxxxxxxxxx> It's about a year since I last mentioned this so I thought I'd give it another go... But the AICA sound driver I wrote for the Dreamcast still won't work properly with a pure ALSA setup and I don't know why. It works when OSS emulation is on so it appears to be some sort of interaction with the ALSA lib layer. The snd-summy driver also appears to work well with a 'pure' ALSA setup, but when (for instance) I try to replay an MP3 track without OSS emulation on I get this: Playing MPEG stream from ms.mp3 ... MPEG 1.0, Layer: III, Freq: 44100, mode: Joint-Stereo, modext: 2, BPF : 2560 Channels: 2, copyright: No, original: Yes, CRC: No, emphasis: 0. Bitrate: 128 Kbits/s, Extension value: 2 Audio: 1:1 conversion, rate: 44100, encoding: signed 16 bit, channels: 2 ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'default' ALSA snd_pcm_hw_params_set_access error: Invalid argument Can't find a suitable libao driver. (Is device in use?) Any clues anyone? Best wishes for 2009 and thanks for all help, Adrian ------------------------------------------------------------------------------ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
