How you are using it, could you share your flowgraph or python script?

The second argument of tch_h_decoder constructor is a string and not a value from the tch_mode enum like the tch_f_decoder constructor. For example see grgsm_decode line 107
$ grgsm_decode --help
--multi-rate=MULTI_RATE

The gsm_tch_h_decoder XML definition is wrong, I'm going to fix it and push a change for review in few hours.
Try to replace lines 22 to 54 with
<param>
<name>MultiRrate configuration</name>
<key>multi_rate</key>
<type>string</type>
<key>multi_rate</key>
<type>string</type>
</param>
And then reinstall - "make && make install" from the build directory

Hi,
Just pushed a change for review https://gerrit.osmocom.org/c/gr-gsm/+/13246
One additional change have to be made, on line 6 replace $mode with $multi_rate
<make>grgsm.tch_h_decoder($sub_channel, $multi_rate, $boundary_check)</make>

Vasil,
can the sub-channel number field changed, that it is possible to enter a string, like in the demapper?

Set "Voice boundary detection" to true. See also https://github.com/ptrkrysik/gr-gsm/issues/451

Yes it can be changed but it's an int and not a string.

Ok, could you share the flowgraph or the python script that you use?

In the gnuradio-companion right-click on the block and select Properties
Right now the parameter's name is different - "TCH/H Channel" in the Demapper block and "sub-channel number" in the Decoder block but I'm going to change both to "Sub-channel number" in https://gerrit.osmocom.org/c/gr-gsm/+/13246
