Re: [LAU] alsaplayer error using USB Audio DAC

Hi All, I'm an alsa novice with a barely surface knowledge of alsa, and I could use some help troubleshooting a problem. I am connecting a Mac Mini (ppc) running the following to a Rega DAC. miniG4:~$ cat /etc/debian_version 6.0.7 miniG4:~$ uname -a Linux miniG4 2.6.32-5-powerpc #1 Fri May 10 08:12:18 UTC 2013 ppc GNU/Linux miniG4:~$ Package: alsa-base Version: 1.0.23+dfsg-2 Package: alsa-utils Version: 1.0.23-3 Package: alsaplayer-common Version: 0.99.80-5+b1 ~/.asoundrc pcm.!default { type hw card 1 } ctl.!default { type hw card 1 } /var/lib/alsa/asound.state state.SoundByLayout { … } state.default { control.1 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'PCM Playback Switch' value true } control.2 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 128' comment.dbmin 0 comment.dbmax 0 iface MIXER name 'PCM Playback Volume' value.0 0 value.1 0 } } I can play audio files through the AppleOnbdAudio - SoundByLayout analog port on the Mini, but when I try to play through USB port, I get the following error. I've peeked into other files, like /proc/asound/*, but I don't really know what to look for. Any pointers would be appreciated short of trying a different Linux distro. The man that sold me the DAC duplicated my system on a G4 MacBook(?) connected to an identical Rega DAC and got it working with relatively little effort. I would be happy to provide additional information at your request. Thanks for your patience. miniG4:~$ alsaplayer flac/ripit/B/Beatles/Let_It_Be..._Naked/10_Across_The_Universe.flac error on set_format SND_PCM_FORMAT_S16 Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: [16 32] CHANNELS: [1 2] RATE: [32000 48000] PERIOD_TIME: [1000 8192000] PERIOD_SIZE: [32 262144] PERIOD_BYTES: [64 524288] PERIODS: [2 1024] BUFFER_TIME: (1333 16384000] BUFFER_SIZE: [64 524288] BUFFER_BYTES: [128 1048576] TICK_TIME: ALL error on set_format SND_PCM_FORMAT_S16 Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: [16 32] CHANNELS: [1 2] RATE: [32000 48000] PERIOD_TIME: [1000 8192000] PERIOD_SIZE: [32 262144] PERIOD_BYTES: [64 524288] PERIODS: [2 1024] BUFFER_TIME: (1333 16384000] BUFFER_SIZE: [64 524288] BUFFER_BYTES: [128 1048576] TICK_TIME: ALL failed to configure output device...trying OSS error on set_format SND_PCM_FORMAT_S16 Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: [16 32] CHANNELS: [1 2] RATE: [32000 48000] PERIOD_TIME: [1000 8192000] PERIOD_SIZE: [32 262144] PERIOD_BYTES: [64 524288] PERIODS: [2 1024] BUFFER_TIME: (1333 16384000] BUFFER_SIZE: [64 524288] BUFFER_BYTES: [128 1048576] TICK_TIME: ALL error on set_format SND_PCM_FORMAT_S16 Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: [16 32] CHANNELS: [1 2] RATE: [32000 48000] PERIOD_TIME: [1000 8192000] PERIOD_SIZE: [32 262144] PERIOD_BYTES: [64 524288] PERIODS: [2 1024] BUFFER_TIME: (1333 16384000] BUFFER_SIZE: [64 524288] BUFFER_BYTES: [128 1048576] TICK_TIME: ALL failed to configure output device...trying OSS miniG4:~$<?xml version="1.0" e
