AUDIO ON LINUX_PPC

AUDIO ON LINUX_PPC

[Stanko Juzbasic]

Is there anybody who encounterde the following problem?
I'm  constantly running into something that seems like a problem with
sound:
1. SOX plays .wav, .au .snd & .aiff files with gaps, whoch looks to me
 like a disagreement on timing issues between the kernel buffer
 &application buffer. (I've recompiled the kernel a few times).

2. CDs from the internal scd drive play flawlessly.

3. Other utilities (such as Wavplay, rawplay) either don't execute, or
don't
 compile, or don't install or refuse to run without Motif (lesstif)
shared
 libraries such as libXm.so.1 etc, which in turn configure but don't
make,
 and give thousands of warnings, hanging in infinite loops...

My platform:  PCI-PowerMac 7200, PowerPC 601 processor.
System:   LINUX_PPC R4, kernel 2.1.24 (configured as standalone
   workstation)
All drives: SCSI

I'd like to know if this is a known problem and if so, is there any hope

this would be resolved for the next release. I'm not concernerd with
8 kHz - 8 bit - 150:1 compressed system beeps. All I care for is playing

plain 16 bit integer linear format files.

That's odd. I have the same soundchip (AWACS) and I do not encounter
these problems. I had my odd problems with soundsoftware, mainly
because of the different endianess of software.
btw, 'sox' (or play) does not work on my machine? endianess I suppose.
I use other software (like wavplay).

Same here.

Maybe you should upgrade your kernel? I don't know about 2.1.24,
but 2.1.125 I use on my 7600 works okay.
I'd still say, try wavplay. It shouldn't need motif or lesstiff
(comment it out).

Comments anyone?
