Description David Flater 2008-10-18 20:06:20 UTC

Arch:     486

Hardware: ISA sound card described as "ESS ES1868 Plug and Play AudioDrive"

Driver:   sound/isa/es18xx.c in mainline 2.6.27.2 kernel

aplay of a 44.1 kHz wav file gets stuck playing a 1/4 or 1/2 second loop at the
beginning.

Source code comments include, "Support for 16 bit DMA seems to be broken."

Reverting to commented-out code as described in the similar story at
http://osdir.com/ml/debian.ports.alpha/2003-06/msg00105.html did not help.

Reducing the wav file to 8 bit samples and mono sound only made the loop
longer.

See also, bug 10214.

Is this a regression?  Did any earlier kernel work OK?  If so, which version(s)?

Thanks.

Comment 2 David Flater 2008-10-22 07:12:57 UTC

I have no prior experience with this sound card, so to answer your question I will test various kernels.  It would help me if you could send me, or give me the command syntax to retrieve, the commit history of sound/isa/es18xx.c.  I will also test OSS if no working ALSA version is found.  Thanks.

The card works well under DOS using the manufacturer's PnP configurator.

I ran into operational problems booting the kernel before I found a version
that works.

Kernels 2.6.27.3 and 2.6.27.2 were compiled with gcc-4.3.2.  All older kernels
were compiled with gcc 4.2.3.  Configs are available on request.

2.6.27.3, 2.6.27.2, 2.6.16.62:  ALSA loops sound as previously described.

2.6.16:  Diff on es18xx.c versus 2.6.16.62 shows only change was a fix for a
memory leak.  Did not test.

2.6.15.7, 2.6.14.7, 2.6.13.5:  Unbootable, stopped after "Freeing unused kernel
memory."  Remains responsive to Shift-PageUp and Ctrl-Alt-Del but otherwise
appears hung.

2.6.12.6:  Unbootable, hung after detecting keyboard.  Detection of keyboard
was reported twice.  Once hung is completely unresponsive to keyboard.

2.6.27.3 (OSS):  There is no ESS module in OSS.  The sb module works for 1-30 s
then the system locks up with HDD LED on.

PC-DOS with C:\ESSCFG.EXE /A:220 /I:5 /D:1 /E:0 /B:300 :  Works.

Linux PnP configurator chooses the same port (220), IRQ (5), and dma1 (1);
however, dma2=3 and mpu_port=330.

Closing as obsolete, if this is incorrect please re-open against a recent kernel
