nc8430 modem geting "period size 48 ..."

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

Having searched through archive I have found a few people having
similar issues. However, My modem ID is different (0x11c13026), which
should be supported:

Current support status of HDA cards is:
Vendor IDs Chip maker Support type
---------- ---------- -------------
0x14f12bfa Conexant hsfmodem , not slmodemd compatible
0x11c13026 AgereSystems snd-hda-intel, slmodemd supported
0x11c11040 AgereSystems " " support not yet available.
0x11c13055 AgereSystems " " , "
0x163c3055 Smartlink " " , "
0x163c3155 " " " , "
0x10573055 Motorola " " , "
0x10573155 " " " , ""
as of October 2006.

Problem I'm having is 'error: period size 48 not supported for
playback (64)' on slmodemd output when trying to dial-out (both kppp
or wvdial cause identical errors).

This is nc8430 running feisty (kubuntu 7.04), with recent scanModem
(few days old).

Please find attached ModemData.txt.

Thank you,
Igor

 For candidate modem in PCI bus:  00:1b.0

                        The HDA card softmodem chip is 0x11c13026

 Lacking a dsp (digital signal processing) chip, the modem is a software 
 intensive or "softmodem" type. Its primary controller manages the traffic 
 with the CPU. But the software needed is specified in the Subsystem.
 -----------------------------------------
Support type needed or chipset:	slmodemd

 An ALSA (Advanced Linux Sound Architecture) modem driver:  snd-intel8x0m
 provides Low Level support enabling contact with the modem hardware.
 For all BUT Conexant chip soft modems (using hsfmodem software)
 complementary High Level support is through a Smartlink utility:  slmodemd

 Download from http://linmodems.technion.ac.il/packages/smartlink/ 
 the package SLMODEMD.gcc4.1.tar.gz having a compiled slmodemd. Unpack under Linux with:
 	$ tar zxf SLMODEMD.gcc4.1.tar.gz
 and read instructions therein. But briefly, the modem is setup with command:
 	sudo slmodemd -c YOUR_COUNTRY --alsa modem:1 
 reporting dynamic creation of ports:
	/dev/ttySL0 --> /dev/pts/N   , with N some number
 Read Smartlink.txt and Modem/YourSystem.txt for follow through guidance.

 Already loaded into the kernel is snd-intel8x0m and audio drivers it depends on,

 Kernel-header resources needed for compiling are not manifestly ready!

 If compiling is necessary packages must be installed, providing:
